عَنْ أَبِي ذَرٍّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: ”إِنَّهَا مُبَارَكَةٌ إِنَّهَا طَعَامُ طَاعِمٍ.“ (يَعْنِي زَمْزَمَ)
It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Zamzam water is blessed and it is food for the eater.
