The Prophets Tahajjud
Hudhaifah (radi Allahu anhu) reported: I offered Salat (Tahajjud) with the Prophet (sal Allahu alaihi wa sallam) one night, and he started reciting (Surat) Al-Baqarah. I thought that he would bow at the end of one hundred Verses, but he continued reciting; I then thought that he would perhaps recite the whole surah in a Rak’ah, but he proceeded on, and I thought he would perhaps bow on completing this surah; he then started An-Nisa’; he then started Al-’Imran and his recitation was unhurried. And when he recited the Verses which referred to the Glory of Allah, he glorified Him, the Great, and when he recited the Verses that mention supplication, he supplicated, and when he recited the Verses that mention seeking Refuge of the Rubb, he sought (His) Refuge. Then he bowed and said: “Subhana Rabbiyal-Azim”; his bowing lasted about the same length of time as his standing (and then on returning to the standing posture after Ruku’) he said: “Sami’ Allahu liman hamidah, Rabbana wa lakal hamd.” Then he stood about the same length of time as he had spent in bowing. He then prostrated himself and said: “Subhana Rabbiyal-A’la,” and his prostration lasted nearly the same length of time as his standing.
This Hadith makes the following three points clear:
Firstly, optional Salat can also be performed in congregation.
Secondly, as is commonly believed, it is not essential that in Salat, the Ayat of Qur’an are recited according to their sequence in the Book. It is permissible to recite them regardless of their sequence in the Qur’an.
Thirdly, it is commendable to relatively prolong the optional prayers.
And Allah Knows Best!
