In The Hadith
Like Quran, the Hadith also mentions and stresses the issue of tawba. In Sahih al-Bukhari, Anas ibn Malik narrates:
Allah's Apostle said, "Allah is more pleased with the repentance of His slave than anyone of you is pleased with finding his camel which he had lost in the desert." —Sahih al-Bukhari, 8:75:321Abu Hurairah narrates:
I heard Allah's Apostle saying." By Allah! I ask for forgiveness from Allah and turn to Him in repentance more than seventy times a day." —Sahih al-Bukhari, 8:75:319Read more about this topic: Repentance In Islam
