However, if a person supplicates in the last rak'ah with a verse [from the Quran, similar to what al-Siddiq did, it has been narrated from Ahmad that he was asked about that. He replied: 'If he wishes, he may say it; and we do not know if that was recitation by Abu Bakr or supplication.'

The entirety of this matter is that covering the nakedness ('awrah) from view with that which does not reveal the skin is obligatory and a condition for the validity of the prayer (1). Al-Shafi'i and the companions of reason (Ashab al-Ra'y) held this view. Some of the companions of Malik said: Covering it is obligatory, but not a condition for the validity of the prayer. Some of them said: It is a condition when one is mindful, not when one is forgetful (2).

(1) After this, the original contains the addition: "according to the opinion of the majority of scholars," then it brings the report from Ibn Abd al-Barr, and it will appear in M later. (2) In the original, the addition: "And some of them said: Covering is obligatory, and not a condition; because its obligation is not exclusive to the prayer, so it is not stipulated for it, like paying off a debt when requested." (3) Omitted from the original. (4) In the original: "And our evidence is the saying of the Prophet (may Allah bless him and grant him peace)." (5) Extracted by Abu Dawud, in: Chapter on a woman praying without a head covering, from the Book of Prayer. Sunan Abi Dawud 1/149. And al-Tirmidhi, in: Chapter on what has been narrated that the prayer of a woman is not accepted except with a head covering, from the Chapters of Prayer. Aridat al-Ahwadhi 2/169. It was also extracted by Ibn Majah, in: Chapter if a girl reaches puberty she does not pray except with a head covering, from the Book of Purification. Sunan Ibn Majah 1/215. And Imam Ahmad, in: al-Musnad 6/150, 218, 259.
