Is Zakah (obligatory charity) due on land intended for selling?
Yes, lands intended for trade are valued, and Zakah is paid according to their estimated value after a lunar year had lapsed, but if the owner didn`t pay the due Zakah, then he should do so after selling them.
What is the ruling on combining more than one intention in the prayer, such as combining the *sunnah* of wuḍūʾ with the pre-Dhuhr *sunnah*, or combining the *sunnah* of greeting the mosque (*taḥiyyat al-masjid*) with the pre-Dhuhr *sunnah*?
All praise is due to Allah, and peace and blessings be upon our master, the Messenger of Allah.
Combining two intentions in a single act of worship, which some jurists call the “overlapping of acts of worship”, has several cases and precise rules. These can be consulted in the books of legal maxims, such as al-Manthūr fī al-Qawāʿid al-Fiqhiyyah by al-Zarkashī and al-Ashbāh wa’l-Naẓāʾir by al-Suyūṭī. Among the most important of these rules:
First: If all of the acts of worship that one wishes to combine under one intention are obligatory, the intentions do not overlap. An example is combining the intention of the obligatory ʿAṣr prayer with that of the obligatory Dhuhr prayer. The intentions do not overlap in this case.
Second: If the two acts are specified supererogatory prayers (nawāfil muqayyadah) that are aimed at in themselves because of a particular time, occasion, or cause, or if they are an obligatory prayer and a specified supererogatory prayer, the intentions again do not overlap. An example is the Duha prayer, which may not be combined with, for instance, the regular sunnah of Dhuhr.
It is stated in Bushrā al-Karīm: “Whatever is not, in meaning, an absolute voluntary prayer, such as the Duha sunnah… is not subsumed under another. Rather, if he intends something else along with it… the prayer is not validly entered. This is because combining two obligations, two specified supererogatory prayers, or an obligation and a specified supererogatory prayer invalidates the prayer in cases not built upon overlapping, as ritual purification (ṭahārah) is.”
Third: If the two acts are absolute voluntary prayers (nawāfil muṭlaqah), or one of them is, where the texts of the Sharīʿah show that the aim of the voluntary act is to fill the time with worship, then overlapping of intentions is permissible. An example is the obligatory Dhuhr prayer together with the sunnah of greeting the mosque (taḥiyyat al-masjid). And Allah Almighty knows best.
Is it permissible to offer mandatory prayer while sitting?
All perfect praise be to Allah, The Lord of The Worlds, and may His Peace and Blessings be upon our Prophet Muhammad and upon all of his family and companions. Standing up is a pillar in the mandatory prayer and the prayer is not valid without it unless one cannot do it. As for Nafila (supererogatory prayer), one can perform it in the state of sitting even if he/she can stand, but his/her reward is half the reward of the person who prays while standing if he/sh has no legal excuse for such an act. And Allah Knows Best.
Is it valid to perform Tarawih prayer at home?
It is Sunnah for a Muslim to perform Tarawih prayer in congregation at the mosque.
However, if a person sometimes prays it at home in congregation with their family for a valid reason, there is no harm in doing so.
