Prescriptions for the Morning and Evening
The noble companion, Abū Ayyūb Ansārī t relates that Rasūlullāh r said, “Whoever recites,
لاَ اِلٰهَ اِلاَّ اللهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَ لَهُ الْحَمْدُ وَ هُوَ عَلىٰ كُلِّ شَيْئٍ قَدِيْرٌ
ten times in the morning, Allāh I writes 10 rewards for each recital. Allāh I also erases 10 sins for each recital, raises him 10 stages and rewards him the equivalent of freeing 10 slaves. The same reward will apply to reciting the same in the evening.” (Musnad Ahmad and Tabrani).
In another hadīth it is said that a person should recite this immediately after the Fajr and Maghrib prayers before adjusting his feet to sit comfortably.
The noble companion, Muslim Ibnul-Hārith At-Taymī t relates that Rasulullah r said, “Recite this dua seven times immediately after the Fajr salah and before talking to anyone
اَللَّهُمَّ أَجِرْنِيْ مِنَ النَّارِ
If you were to die on that day, Allāh I will write down that you are to be saved from the Fire.” (Musnad Ahmad, Abū Dāwūd, and Tirmidhī) C
