وَعَنْهَا أَنَّ النبى صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: “إِنَّ الرِّفْقَ لاَ يَكُونُ فِي شئ إِلاَّ زَانَهُ، وَلاَ يُنْزَعُ مِنْ شئ إلا شانه” ((رَوَاهُ مُسْلِم)).
'Aishah (May Allah be pleased with her) reported: The Prophet (ﷺ) said, "Whenever forbearance is added to something, it adorns it; and whenever it is withdrawn from something, it leaves it defective." [Muslim].
