It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever drinks water on an empty stomach, his strength decreases."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these hadiths from Zayd bin Aslam (may Allah have mercy on him) except his son Abd al-Rahman (may Allah have mercy on him), and Abu Aslam is alone in narrating them."
