What are the Sunnahs and etiquettes recommended for the person offering the Udhiyah?
In the Name of Allah, and may peace and blessings be upon our Master, the Messenger of Allah.
There are several Sunnahs (prophetic traditions) and etiquettes that are highly recommended for the person offering an Udhiyah (sacrificial offering) to observe:
First:
It is a Sunnah for anyone intending to offer a sacrifice to refrain from cutting or removing any of their hair or nails once the first ten days of Dhul-Hijjah begin. This is based on the statement of the Prophet (peace and blessings be upon him): "When the ten days [of Dhul-Hijjah] begin and one of you intends to offer a sacrifice, let him not touch any of his hair or skin." (Narrated by Muslim)
However, if someone does happen to remove any hair or nails, they have not committed a sin, and their sacrifice remains perfectly valid.
Second:
The person offering the sacrifice should ideally slaughter the animal themselves. If they are unable to do so, they should at least witness its slaughter. This is drawn from what our Master, the Messenger of Allah (peace and blessings be upon him), said to Lady Fatima (may Allah be pleased with her):
"Stand up and witness your sacrifice, for with its very first drop of blood, every sin you have committed will be forgiven." (Narrated by Al-Tabarani in his Mu'jam, Al-Hakim in his Mustadrak, and Al-Bayhaqi in his Sunan)
Third:
Face the Qiblah (the direction of prayer) at the time of slaughtering, as the Qiblah is the most honorable of directions.
Fourth:
Pronounce the name of Allah (Tasmiyah) at the moment of slaughter by saying: "Bismillah ar-Rahman ar-Rahim" (In the Name of Allah, the Most Gracious, the Most Merciful). Even if one forgets to say it, the meat remains lawful (Halal) to eat. Allah, Blessed and Exalted is He, says:
"So eat of that [meat] upon which the name of Allah has been mentioned." (Al-An'am: 118)
It is also recommended to send blessings upon our Master, the Messenger of Allah (peace and blessings be upon him), and to follow it with the Takbeer (Allahu Akbar).
Fifth:
Supplicate for acceptance by saying: "Allahumma hadhihi minka wa ilayka, fa-taqabbal minni" (O Allah, this is a blessing from You and is offered back to You, so please accept it from me). This means: This sacrifice is a blessing that originated from You, and I am offering it to draw closer to You. And Allah the Almighty Knows Best.
What is the ruling of Islamic Law on supplicating with other than the transmitted (Ma'thur) supplications in prayer?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
It is permissible to supplicate (make du'a) during the prayer for anything from the affairs of religion or worldly life, and the prayer is not invalidated by doing so.
Shaykh al-Islam, the Imam an-Nawawi, may Allah have mercy on him, says: "Our madhhab [i.e., the Shafi'i madhhab] holds that it is permissible for a person to supplicate during it [the prayer] with anything that is permissible to supplicate with outside the prayer, from the affairs of religion or worldly life. He may say: 'O Allah, grant me wholesome sustenance, offspring, a house, and a beautiful young wife' — describing her; or: 'O Allah, free so-and-so from prison,' or 'destroy so-and-so,' and other such things — and none of this invalidates his prayer according to us. And this is also the view of Malik, ath-Thawri, Abu Thawr, and Ishaq." [Al-Majmu', Vol.3/P.454]. And Allah, the Exalted, knows best.
What is the ruling on performing the night prayer (*qiyām al-layl*) between the first and second adhān of Fajr? And which is better: delaying the prayer until shortly before the Fajr adhān, or performing it earlier than that?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
The time for night prayer (qiyām al-layl) begins after the Maghrib prayer and lasts until the second adhān of Fajr. The best time for it is the last third of the night, and best of all are the fourth and fifth sixths of the night. If the night is divided into two halves, the latter half is better.
Whoever intends to pray at night is encouraged to delay the Witr until he has prayed the night prayer. If he knows that he will not wake up, it is better for him to pray and perform Witr before sleeping, so that he does not miss both the night prayer and the Witr.
It is stated in Mughnī al-Muḥtāj (Vpl.1/p.462): “I say: The voluntary prayer of the night, that is, the absolute voluntary prayer (al-nafl al-muṭlaq), is better than the absolute voluntary prayer of the day, because of the report in Muslim: ‘The best prayer after the obligatory prayer is the night prayer.’ In another narration of his: ‘In the night there is an hour that no Muslim man meets while asking Allah for any good of this world and the next except that He gives it to him, and that is every night.’ It is also because the night is a time of heedlessness. I restricted the voluntary prayer to the absolute kind following the commentator, although what the ḥadīth and the underlying meaning require is that the night rawātib be preferred over the day rawātib, since the jurists preferred the two rakʿahs of Fajr over everything except Witr. The middle of the night is better than its two ends if it is divided into thirds, because heedlessness is greatest then and worship is hardest. If he wishes to pray during some third, the best is the fourth and fifth sixths, based on the ḥadīth in the two Ṣaḥīḥs: ‘The most beloved prayer to Allah the Exalted is the prayer of Dāwūd: he would sleep half the night, stand for a third of it, and sleep for a sixth.’ Then the latter part is better than the first if he divides it into two halves, because of the saying of Allah the Exalted: ‘And in the hours before dawn they would ask forgiveness’ [al-Dhāriyāt: 18], and the report of the two Shaykhs: ‘Our Lord, Blessed and Exalted, descends,’ meaning His command descends, ‘to the lowest heaven when the last third of the night remains, and says: Who calls upon Me, that I may answer him? Who asks of Me, that I may give him? Who seeks My forgiveness, that I may forgive him?’”
It is also stated in ʿUmdat al-Sālik (p. 60): “It is better to perform it [the Witr] immediately after the sunnah of ʿIshāʾ, unless he has tahajjud, in which case it is better to delay it so that he performs Witr after it. If he performs Witr and then wishes to pray tahajjud, he prays two rakʿahs at a time and does not repeat the Witr, nor does he need to cancel it with a single rakʿah before the tahajjud. It is recommended that he not deliberately pray after it.”
Qiyām al-layl is a term applied to any prayer performed at night. Tahajjud, on the other hand, refers to the night prayer that follows sleep, whether it is prayed after Maghrib or after ʿIshāʾ, or the prayer performed after ʿIshāʾ without sleep. On this basis, the Witr is also called tahajjud, since it is only prayed after ʿIshāʾ.
It is stated in al-Majmūʿ (Vol.4/p.84): “The sound position, as stated in al-Umm and al-Mukhtaṣar, is that the Witr is called tahajjud.”
It is stated in Nihāyat al-Zayn (Vol.1/p.114): “Among the absolute voluntary prayers is qiyām al-layl. If it is performed after sleep, even during the time of Maghrib and after having prayed ʿIshāʾ early (taqdīman), it is called tahajjud.”
And it is stated in Ḥāshiyat al-Bujayrimī ʿalā al-Khaṭīb (Vol.1/p.418): “His statement: ‘(the night prayer)’: the genitive construction (iḍāfah) carries the sense of fī, meaning a prayer in the night. His statement: ‘(it would be more fitting)’: the reason it is more fitting is that the night prayer includes both tahajjud and other prayers.” And Allah Almighty knows best.
Is it permissible for one to shake hands with his uncle`s daughter?
No, it isn`t because he is a non-Mahram (Marriageable) to her.
