It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once, while I was praying with the Messenger of Allah (peace and blessings be upon him), a man from the gathering said these words: 'Allahu akbaru kabira, wal-hamdu lillahi kathira, wa subhan Allahi bukratan wa asila' (Allah is the Greatest, greatly; all abundant praise belongs to Allah; and Allah is free of every imperfection, morning and evening). When the Messenger of Allah (peace and blessings be upon him) had completed the prayer, he asked: "Which of you is the one who said these words?" The people remained silent. Then a man said: O Messenger of Allah (peace and blessings be upon him)! I said them, and I intended nothing but good by them. So the Messenger of Allah (peace and blessings be upon him) said: "The gates of the heaven were opened for these words." Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "Since I heard the Messenger of Allah (peace and blessings be upon him) say this, I have never abandoned these words."
