Sayyiduna Sa’d (may Allah be pleased with him) narrates that I submitted,“O Messenger of Allah (peace be upon him), my mother has passed away. Should I give charity on her behalf?”The Prophet (peace be upon him) said,“Yes, do so.”I asked,“Which charity is best?”The Prophet (peace be upon him) said,“Providing water (i.e., have a well dug and dedicate it as a waqf).”

Sayyiduna Sa’d bin ‘Ubadah (may Allah be pleased with him) narrates that I asked,“O Messenger of Allah (peace and blessings be upon him), which charity is best?”He (peace and blessings be upon him) replied:“Providing water is best.”
