Fath al-Rabbani

Abdur Rahman says that the mention of Laylat al-Qadr was made in the presence of Sayyiduna Abu Bakr (may Allah be pleased with him). He said: I will seek this night only in the last ten nights, because I heard the Prophet (peace and blessings be upon him) say: Seek it in the odd nights of the last ten nights. The practice of Sayyiduna Abu Bakr (may Allah be pleased with him) was that during the first twenty days of Ramadan, he would pray according to his routine for the whole year, but when the last ten nights began, he would exert himself greatly in worship.
