Marwan ibn Salim al-Muqaffa' said:

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.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ يَحْيَى أَبُو مُحَمَّدٍ، حَدَّثَنَا عَلِيُّ بْنُ الْحَسَنِ، أَخْبَرَنِي الْحُسَيْنُ بْنُ وَاقِدٍ، حَدَّثَنَا مَرْوَانُ، - يَعْنِي ابْنَ سَالِمٍ - الْمُقَفَّعُ - قَالَ 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 " .
