Uyayriah ibn Abdur Rahman (RA) reported that his father said that before Sayyidina Abu Bakr (RA) So, he said, “I have ceased to look out for it since I heard from Allah’s Messenger (SAW) that it is in the last ten (days). I heard him say, “Seek it when nine nights remain, or seven remain, or five remain, or three, or the last night”. Abu Bakr used to pray during the twenty (nights) of Ramadan as he prayed all through the year, but when the last ten days began, he became more devoted”.
