'Abdullah bin 'Umar bin Al-Khattab (May Allah be pleased with them) reported that:
The Prophet ﷺ said, "Allah accepts a slave's repentance as long as the latter is not on his death bed (that is, before the soul of the dying person reaches the throat)".

[At-Tirmidhi, who categorised it as Hadith Hasan].

وعن أبي عبد الرحمن عبد الله بن عمر بن الخطاب رضي الله عنهما عن النبي ﷺ قال: " إن الله عز وجل يقبل توبة العبد ما لم يغرغر" ((رواه الترمذي وقال: حديث حسن)).
