1. It is permissible for you to perform Hajj with your uncle’s money. However, it is important to clarify if the money is a loan or a gift. It cannot be suspended between the two, gift if you die in Hajj or otherwise a loan. The amount should either be a loan or a gift. If it a loan, your uncle may forfeit his claim on the loan.
2. It is permissible for a woman to shave her legs.
3. Singing without music is permissible on condition the song does not contain anything un-Islamic in it. For example, it must not be a song that is normally played with music, it must not have a tone of a music song. There must not be any immoral contents in the song. Poetry (She’r) and Nazms (songs) are meant to refreshen a person’s Imaan and enhance one’s love for Islam, Allah and His Rasul [sallallaahu alayhi wasallam].
