Ibn ‘Abbas said:The Prophet(ﷺ) lifted the curtain (and saw that) the people were standing in rows(of prayers) behind Abu Bakr. He said: O people, there remained nothing that gives good tidings from prophethood except a true dream which a Muslim has himself or which another Muslim has for him. I have been prohibited to recite the Qur’an while bowing or prostration. As regards owing, exalt the Lord in it, and as to prostration, make supplication with exertion in it, that is worthy of being accepted
