Question: I made a vow that if my work is done i will pray tahajjud regularly,500 times durood daily and fininsh QURAN every month.i have been unable to keep my vows after my work was done.i try to do all these things but can not complete them what is my expiation
Answer: Assalamu alaikum wa rahmatullah,
I pray this finds you in the best of health and states.
Such a statement is a religious vow (nadhr), yet its form is a conditional statement that one wants to occur (namely, doing one’s work).
The ruling for this statement is that if one does one’s work, then one must fulfill the vow. So it would be mandatory for you to pray tahajjud regularly, do 500 durud daily, and finish the Qur’an every month.
There is no expiation in your case; you must try your best to stick to the vow, as it is mandatory.
