التواب
التوبةُ هي الرجوع عن الذَّنب، و(التَّوَّاب) اسمٌ من أسماء الله...
Jundub ibn ‘Abdullāh (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "A man said: 'By Allah, Allah will not forgive so-and-so.' Thereupon, Allah said: 'Who is that who swears that I will not forgive so-and-so? Indeed, I have forgiven him and rendered worthless your deeds.'" In a similar Hadīth reported by Abu Hurayrah: ''The sayer was a worshiper.'' Abu Hurayrah said: ''He said a word that ruined his life and Hereafter.’'
شرح الحديث :
Warning against the dangers of the tongue, the Prophet (may Allah's peace and blessings be upon him) says that a man once swore that Allah would not forgive a sinner. It was as if he was passing a judgment that limits Allah's authority, believing in his credit and the sinner's disgrace. His conceit implies his rudeness toward Allah, a practice that subjected him to a miserable fate in life and the Hereafter.
