Jami` at-Tirmidhi Book 48, Hadith 190
That the Messenger of Allah (ﷺ) said: “He who seeks forgiveness has not been persistent in sin, even if he does it seventy times in a day.”
“Abu Bakr stood upon the Minbar, then wept, and said: ‘The Messenger of Allah (ﷺ) stood upon the Minbar the first year (of Hijrah), then wept, and said: “Ask Allah for pardon and Al-`Āfiyah, for verily, none has been given anything better than Al-`Āfiyah.’”
That `Umar bin Al-Khattab wore a new garment and said: “All praise is due to Allah who clothed me with what I may cover my `Awrah, and what I may beautify myself with in my life (Al-ḥamdulillāh, alladhī kasānī mā uwārī bihī `awratī, wa atajammalu bihī fī ḥayātī).” Then he said: “I heard the Messenger of Allah (ﷺ) saying: ‘Whoever wears a new garment and then says: “Allah praise is due to Allah who clothed me with what I may cover my `Awrah and what I may beautify myself with in my life (Al-ḥamdulillāh, alladhī kasānī mā uwārī bihī `awratī, wa atajammalu bihī fī ḥayātī)” and then he takes the garment that has worn out and gives it in charity, he shall be under Allah’s guard, Allah’s protection, and Allah’s covering, alive and dead.’”
