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 for a woman to shake hands with her brother-in-law?

Does tooth extraction during the day in Ramadan break the fast?
Simply extracting a tooth during the day in Ramadan does not break the fast. However, if water or blood enters the body cavity, the fast becomes invalid.
Whoever's fast is invalidated in this way must refrain from eating and drinking for the rest of the day out of respect for the sacred month and make up for that day later.
It is preferable to postpone the extraction until nighttime or after Ramadan if possible.
When is Istikharah (guidance prayer) Du`a offered, before Tasleem (saying asalamu alikum warahmatu allah wa barakatuh to end the prayer), or after it?
It is offered after Tasleem.
