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.
Hadith Commentary: Sunan Abi Dawud 2357
This narration from Abdullah ibn Umar (may Allah be pleased with him) contains two distinct prophetic practices: the trimming of the beard and the supplication upon breaking the fast.
Scholarly Analysis of Beard Trimming
The action of Ibn Umar holding his beard and cutting what exceeded a handful demonstrates the sunnah method of beard grooming. Classical scholars like Imam Nawawi explain that the recommended length is what fits within one hand when grasping the beard. This practice preserves the natural form while maintaining neatness.
Imam Malik and Imam Ahmad emphasized that completely shaving the beard is prohibited (haram) as it contradicts the prophetic command to grow the beard. The permissible trimming applies only to excess length beyond the fistful measure.
Commentary on the Breaking Fast Supplication
The supplication "Thirst has gone, the arteries are moist, and the reward is sure, if Allah wills" (Dhahaba al-zamā'u wa-btallati al-'urūqu wa-thabata al-ajru in shā' Allāh) contains profound spiritual wisdom.
Ibn al-Qayyim explains in "Zad al-Ma'ad" that this du'a acknowledges the physical relief from thirst, the spiritual renewal through worship, and the hopeful anticipation of divine reward - all conditioned by Allah's will (in sha Allah).
Al-Khattabi notes that "the arteries are moist" signifies the restoration of bodily fluids and vitality after dehydration, reminding Muslims of Allah's mercy in providing relief.
Juridical Rulings from Fasting (Kitab Al-Siyam)
This hadith appears in Sunan Abi Dawud's chapter on fasting, indicating its primary relevance to iftar etiquette. Scholars classify this supplication as recommended (mustahabb) but not obligatory.
The timing for this du'a is immediately upon breaking the fast, before the sunset prayer (Maghrib). Ibn Hajar al-Asqalani emphasizes that combining physical nourishment with spiritual remembrance exemplifies the comprehensive nature of Islamic worship.
