Question:
Asalamualaikum, i wanted to know if anyone of us makes a pledge or vow sort of that if some of our worldly task gets accomplished by ALLAH 
we will start performing a particular amal, e.g. suppose i say to myself if i pass this exam i will start doing this and that amal (deeni deed ),or if i get selected i will start reciting tasbih in the morning and evening etc. My question is, is it right on our part to make such vows?
Answer:
In the name of Allah, the most Beneficent, the most Merciful.
There are two kinds of vow (Nadhr):
- Conditional vow, for example, one says: “If I recover from my illness, it will be obligatory upon me to do a certain worship for the pleasure of Allah.” When this condition is found that act of worship will become obligatory.
- Absolute or unconditional vow; in this case, one says without any conditions: “I make a vow for the pleasure of Allah to offer two rakaats Salah.” As soon as he makes this vow, it becomes obligatory to perform it.
There is one opinion of Imam Abu Hanifa 
that a vow whether it is conditional or unconditional it becomes obligatory to fulfil. (Mukhtasar Quduuri p.204)
The conclusion of your question will be is that as soon as the condition is found the act of worship will be obligatory. It will also be correct to start the fulfilling of the vow now as one opinion of Imam Abu Hanifa (RA) is that it becomes obligatory as soon as the vow is made irrespective of whether the vow has been found or not.
