When Laylat al-Qadr was mentioned in the presence of Sayyiduna Abu Bakrah (may Allah be pleased with him), he said: "I seek it only in the last ten, on account of a hadith I heard from the Messenger of Allah (peace and blessings be upon him). I heard him (peace and blessings be upon him) say: 'Seek it in the last ten nights, when nine (nights of the month) remain, or seven remain, or five remain, or three remain, or on the last night.'" The narrator states that in the first twenty days of Ramadan Sayyiduna Abu Bakrah (may Allah be pleased with him) would pray as usual, like the rest of the year, but when the last ten began he would strive hard and exert himself (in worship). This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs did not record it.
