i am belongs to Islam (non creamy layer) community. For OBC reservation I have to attach caste certificate or non creamy layer certificate.
You have to attach OBC Non Creamy Layer certificate because it is the proof that your annual income is less than 6 lakh rupees. Only those candidates whose family income is less than 6 lakhs come under OBC Non creamy layer. Your caste certificate is not enough proof of OBC NCL. So you should uplosd OBC Non creamy layer certificate only.
