Narrated Buhaisah:
On the authority of her father: My father asked the Prophet ﷺ for permission (to kiss his body). (When he was given permission), lifting his shirt he approached his body, and began to kiss and stick to him. He then asked: Prophet of Allah, what is the thing withholding of which is not lawful ? He replied: Water. He asked: Prophet of Allah, what is the thing withholding of which is not lawful ? He replied: Salt. He again asked: Prophet of Allah, what is the thing withholding of which is not lawful ? He said: That you do a good work is better for you.
