What should a person, who doubts the validity of his Wudu, or over performs it, do?
One who doubts the validity of his/her Wudu while performing it should redo it until he/she is certain of having attained purity. But, if doubt was after having performed Wudu, then he/she should not pay attention to that as doubt after the end of an act of worship does not count. This is of course in case doubt was within the reasonable limits since once it goes beyond that, it becomes a whispering of the Shaytaan (devil) which he/she should ignore as the Wudu is valid.
What is required of one who doubts the number of rakʿāt during prayer?
All praise is due to Allah, and peace and blessings be upon our master the Messenger of Allah ﷺ.
If a person doubts the number of rakʿāt he has prayed, he should build upon the lesser number, as that is what he is certain of. He should then perform the prostration of forgetfulness (sujūd al-sahw) before the final salām at the end of the prayer. ʿAṭāʾ ibn Yasār narrated that the Messenger of Allah ﷺ said: "When any one of you is in doubt during his prayer and does not know whether he has prayed three rakʿāt or four, let him pray one more rakʿah and then perform two prostrations while seated before the salām. If the rakʿah he prayed was a fifth, these two prostrations will make it even; and if it was the fourth, then the two prostrations serve as a humiliation for the devil." (Reported by Abū Dāwūd.)
It is stated in al-Muqaddimah al-Ḥaḍramiyyah — one of the foundational texts of the Shāfiʿī school: "If one doubts whether he has prayed three rakʿāt or four, he is obliged to build upon the lesser number."
However, if such doubt recurs repeatedly and reaches the level of obsessive whispering (waswasah), he should not build upon the lesser number in that case — rather, he should build upon the greater number. And Allah the Almighty knows best.
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.
What is the ruling of Islamic Law on the prayer of zawal?
All praise is due to Allah, and peace and blessings be upon our master the Messenger of Allah ﷺ.
It is recommended (sunnah) to pray four rakʿāt — either with a single tasleem or as two separate sets of two rakʿāt — immediately following the sun's decline from its zenith (zawāl). This prayer is distinct from the regular Sunnah prayer of Ẓuhr (sunnat al-ẓuhr al-rātibah), as explicitly stated by the Shāfiʿī jurists.
It is mentioned in Nihāyat al-Muḥtāj: "The prayer of zawāl is offered after the sun's decline — so were one to perform it before that, it would not count. It consists of two or four rakʿāt and is distinct from the Sunnah of Ẓuhr, as is evident from the fact that it is mentioned separately after the regular Sunnah prayers, and it becomes a make-up prayer (qaḍāʾ) if a long period of time passes by customary reckoning... Al-ʿAlqamī stated: 'Scholars refer to this as the Sunnah of Zawāl, and it is distinct from the four rakʿāt that constitute the Sunnah of Ẓuhr.' Our shaykh said: Al-Ḥāfiẓ al-ʿIrāqī stated that among those who explicitly affirmed its recommendation was al-Ghazālī in al-Iḥyāʾ, in the chapter on devotional litanies, noting that there is no tasleem between them — meaning there is no break between each pair of rakʿāt."
The time of the sun's decline (zawāl) marks the very beginning of the time for the Ẓuhr prayer.
And Allah the Almighty knows best.
