ABUDAWUD 2357:
from al-Kaf —
I saw Ibn Umar holding his beard with his hand and cutting what exceeded the handful of it. He (Ibn Umar) said that the Prophet ﷺ said when he broke his fast: Thirst has gone, the arteries are moist, and the reward is sure, if Allah wills.
أبو داود ٢٣٥٧:
عن الكف —
رَأَيْتُ ابْنَ عُمَرَ يَقْبِضُ عَلَى لِحْيَتِهِ فَيَقْطَعُ مَا زَادَ عَلَى الْكَفِّ وَقَالَ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا أَفْطَرَ قَالَ ذَهَبَ الظَّمَأُ وَابْتَلَّتِ الْعُرُوقُ وَثَبَتَ الأَجْرُ إِنْ شَاءَ اللَّهُ
