Al-Adab Al-Mufrad, Hadith 229 ⓘ
Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "A man came across a thorn in the road and said, 'I will remove this thorn so that it does not harm a Muslim man.' For that reason he was forgiven."
حَدَّثَنَا مُوسَى، قَالَ: حَدَّثَنَا وُهَيْبٌ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: مَرَّ رَجُلٌ مُسْلِمٌ بِشَوْكٍ فِي الطَّرِيقِ، فَقَالَ: لَأُمِيطَنَّ هَذَا الشَّوْكَ، لاَ يَضُرُّ رَجُلاً مُسْلِمًا، فَغُفِرَ لَهُ.
