[As a rule] it is permissible [for a man] to pray the voluntary prayer – such as the taraaweeh – at home.
[As a rule] there is no harm in you praying it (the taraaweeh prayer) at home, since it is [a] voluntary [prayer].
[Regarding] the ‘umrah, if he (the son) wants to gift [the reward of] an ‘umrah to his deceased father, even though he (the father) had done ‘umrah himself…
Some of the scholars say that the Prophet (sal-Allaahu ’alayhi wa sallam) granted permission for the hajj to be performed on behalf of the deceased – without [specifically mentioning] the ‘umrah.
My mother died whilst I was young, and so I hired someone trustworthy to perform hajj on her behalf. My father had also died, and I heard from some of my relatives that he himself had performed the hajj.
Whoever undertakes a vow to perform hajj, and subsequently dies [without having done so], and leaves no estate [from which funds can be set aside for the hajj], would the performance of hajj on his behalf be considered a recommendation or an obligation?
