“I was sitting with Ibn ‘Abbas, and a man came to him and he said: ‘Where have you come from?’ He said: ‘From Zamzam.’ He said: ‘Did you drink from it as you should?’ He said: ‘How is that?’ He said: ‘When you drink from it, turn to face the Qiblah and mention the name of Allah, drink three draughts and drink your fill of it. When you have finished, then praise Allah.’ The Messenger of Allah ﷺ said: ‘The sign (that differentiates) between us and the hypocrites is that they do not drink their fill from Zamzam.” (Using translation from Ibn Mājah 3061)   

إِذَا شَرِبْتَ مِنْهَا فَاسْتَقْبِلِ الْقِبْلَةَ وَاذْكُرِ اسْمَ اللَّهِ وَتَنَفَّسْ ثَلَاثًا وَتَضَلَّعْ مِنْهَا فَإِذَا فَرَغْتَ مِنْهَا فَاحْمَدِ اللَّهَ فَإِنَّ رَسُولَ اللَّهِ ﷺ قَالَ «آيَةٌ بَيْنَنَا وَبَيْنَ الْمُنَافِقِينَ أَنَّهُمْ لَا يَتَضَلَّعُونَ مِنْ زَمْزَمَ»
