Hadith 23232

حَدَّثَنَا وَكِيعٌ ، حَدَّثَنَا شُعْبةُ ، عَنْ يَحْيَى بنِ حُصَيْنٍ ، عَنْ جَدَّتِهِ ، قَالَتْ : سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يَقُولُ : " يَرْحَمُ اللَّهُ الْمُحَلِّقِينَ ، يَرْحَمُ اللَّهُ الْمُحَلِّقِينَ ، يَرْحَمُ اللَّهُ الْمُحَلِّقِينَ " ، قَالُوا فِي الثَّالِثَةِ : وَالْمُقَصِّرِينَ ؟ قَالَ : " وَالْمُقَصِّرِينَ " .
Yahya bin Husain (may Allah have mercy on him) narrates from his grandmother that I heard the Noble Prophet (peace and blessings be upon him) say three times: "May Allah's mercy descend upon those who shave their heads." The third time, people requested that those who shorten their hair also be included in the supplication, so the Noble Prophet (peace and blessings be upon him) included them as well.
