ANSWER:

There’s no specific dua mentioned, just make general dua during times of acceptance, such as in salah in your sujood, in the last tashahud, before making salam, between Azaan and iqama, during the last third of the night, begging Allah until He opens the door and answers your dua.

My uncle is a taxi driver here in the UK. He takes people to their school, work, home and also to clubs and pubs where the his passengers drink alcohol and do other haram things but he only drops them off outside and carries on his work. He told me that he is to pay a monthly subscription for me to have some dietary food and drink. Is it halal for me to eat and drink this.
