Salam! I want to ask a question related to the disagreement between shia and suni islam, the question is there are numerous ahadith in shia islam about the presence of imam e zamana (عليه السلام) but we can't satisfy our sunni brothers by those ahadith because they generally don't accept our ahadith and our books so in order to convince a suni brother, is there any logical reason?? About the presence of imam mahdi (عليه السلام)??? a reason that will make them realize about the presence of Imam Mahdi (عليه السلام).. so that i can convince my suni brothers in this topic, because this is very important topic in our beloved religion Islam... kindly help me in this issue. JazakAllah
