2. There are some words, the reciters of which will never be disappointed. These are: Tasbih [saying 'Subhan-Allah' (Allah is free from imperfection)], 33 times, Tahmid [saying 'Al-hamdu lillah' (praise be to Allah)] 33 times and Takbir [saying 'Allahu Akbar' (Allah is Greatest)] 34 times; and these should be recited after the conclusion of every prescribed prayer.
[Riyad as-Salihin - Book 16, Hadith 13]
3. How beautiful is it that Allah will eagerly forgive you for the things you can't even forgive yourself for.
4. By saying: Subhan Allah a hundred times, then one thousand good deeds will be recorded for him or one thousand sins will be blotted out from his record.
[Riyad as Salihin:Book 16, Hadith 24]
5. (Quran 5:39)
"But whoever repents after his wrongdoing and reforms, indeed, Allah will turn to him in forgiveness. Indeed, Allah is Forgiving and Merciful."
