«العمرى جائزة لمن أعمرها والرقبى جائزة لمن أرقبها والعائد في هبته كالعائد في قيئه»
The Prophet (peace and blessings be upon him) said:
"The 'umra is valid for the one to whom it is granted, and the ruqba is valid for the one to whom it is granted; and the one who takes back his gift is like one who takes back his own vomit."
