Urine drops while performing saee

Q: I have illness of urine drops and I am in umrah. During umrah, after I completed my tawaaf and went to saee, I feel drops come out on my ihraam. After I completed 1 round of saee, I went to the washroom to wash my ihraam. I made wuzu and again went for saee and started again from my second round and completed it. Is my saee valid?

Taking an oath on anyone besides Allah Ta'ala

Q: I just came to know yesterday that taking a qasam of ghairullah (anyone besides Allah) is not allowed in Islam.

I don't remember taking a qasam of ghairullah but I have a doubt that years ago I might have asked someone in texting to take a qasam of his mother and he refused to take it. I was ignorant about it. What should I do now?

Is asking someone to take qasam of his mother is also sin? although he refused to take it. 

Hajj-e-badal

Q: I am looking for a good source for Haj-e-Badal. I have performed my Haj and have wish to perform Haj for my dad who is no more. I will be doing it with my money, so I believe I can do Haj-e-Tamattu also. Please correct me if I am wrong.
