once Abu Hanifah saw him praying and was left perplexed by it. When the Imam completed the prayers he said, “O Aba Abdillah! How torturous is your prayer!” Imam (a.s) replied, “Don’t you know that among all the worship acts, prayer is the greatest cause of divine proximity?”
Imam Ja’far as-Sadiq (a.s) used to prolong the recitations of his bowing (ruku) and prostration (Sajdah) so much that sometimes he recited them more than sixty times. The narrator says: One day I went to Imam (as.) to inquire something from him. I found him lying in prostration in the Prophet’s mosque. I sat down near him thinking that when he completes his prayer I can ask him the question. The Imam prolonged the prostration so much that I was fed up sitting there. I thought up of some idea to somehow convey to him that I was present there. I decided to also go into prostration and recite the recitation of prostration loudly so that the Imam would hear my voice and complete his prayer. Thus I began to pray and when I went into prostration I recited the recitation loudly. When I had recited it more than 360 times I realized that the Imam has concluded his prayer. I also concluded my prayer then addressed the Imam, “Master, if this is the level of your prayer, what is the worth our prayers?” He said, “More or less, both are accepted from our Shias (followers)”
One day the Imam was passing by the orchards of Kufa. After walking for sometime he sat under a date palm. There he performed the ritual ablution and began to pray. He prolonged the recitation of his prostration so much that it exceeded five hundred times.
