Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) lifted the curtain of his blessed chamber while the companions were standing in rows behind Sayyiduna Abu Bakr (may Allah be pleased with him) (performing prayer), so the Prophet (peace and blessings be upon him) said: "O people, among the glad tidings of prophethood, only righteous dreams remain, which a Muslim will see or will be shown to him. Beware, indeed I have been forbidden from reciting (Qur'an) in the state of bowing and prostration, therefore, in bowing, glorify the greatness of your Lord, and in prostration, supplicate earnestly and diligently, for it is most likely that your supplications will be accepted." This is the hadith of Abdul Jabbar.
