Assalamu alaikum I don't know I made a promise to allah or not when I was suffered some serious waswas problems . I thought may be leather used in my country are from pigs so I'm worried and abstained from using any leather products.but now I realize most of them are made from Cattles so my doubt is about gone. But I'm worried about my past that may be I made a promise to allah that I will have use leather products bcz Here it is difficult to avoid leather so so I say myself and to allah that "first of all I don't know whether the leather is made from synthetic or genuine source,if it is genuine I don't know it is from pig or not,so even for a doubt I'm doing these much (abstaining from using/buying leather) so if any case I come contact with pig leather Allah forgive me " and I pray to allah for forgiveness if I touch it ? Now I want to use it so does this count as a promise ? Please reply me I'm suffering alot ...May Allah bless you
If you didn't know about it beforehand than Allah will forgive you and not punish you. If you now know of it you must avoid it since its impure and ask forgiveness. If you don't get help from people about it search online for it and as far as I know pig leather are known to be expensive, there is other and better alternatives.
