“Once we went to visit abu ‘Abd Allah (a.s.), when there a group of people was with him. He (the Imam) performed al-’Asr Salah (prayer) with them and we had already performed our Salah (prayer). We counted the number of Tasbih (my Lord, (Allah) most Great, is free of all defects) thirty- three or thirty-four times. One of them (narrators) in his Hadith has said that the number of his Tasbih (my Lord, (Allah) most Great, is free of all defects and I praise Him) in both Ruku’ and Sujud (prostration) were of the same number. This is because he (the Imam) knew they were ready for lengthy Ruku’ and Sujud (prostration). This also is because of a Hadith that it is better for an Imam to make it light and perform Salah (prayer) according to the condition of the weakest of the people (performing Salah (prayer) with him).”’
