Al-Adab Al-Mufrad, Hadith 31 ⓘ
Ibn 'Umar said, "Making parents weep is part of disobedience and one of the major wrong actions."
حَدَّثَنَا مُوسَى، قَالَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ زِيَادِ بْنِ مِخْرَاقٍ، عَنْ طَيْسَلَةَ، أَنَّهُ سَمِعَ ابْنَ عُمَرَ يَقُولُ: بُكَاءُ الْوَالِدَيْنِ مِنَ الْعُقُوقِ وَالْكَبَائِرِ.
