He reported God's Messenger as saying:: “If anyone recites in the morning Hā Mīm al-Mu’min (Al-Qur’ān, 40:1-3) to ‘to Him is the final goal’ and the Throne Verse (Al-Qur’ān, 2:255) he will be guarded by them till the evening, and if anyone recites them in the evening he will be guarded by them till the morning.” Tirmidhī and Dārimī transmitted it, Tirmidhī saying this is a gharīb tradition.
