I believe miracles have a place in today's time too not just the future and the past, and it's alluded that Imam Mahdi will show the miracles, if we pray to God frequently both in Quran and ahadith. Du'a arifina nafsika is clear, but also Quran when it has discussed the signs said for every people there is a guide that can show these signs and who the signs prove and else where it said the hiding is up to God and else where said about them asking for such clear proof, he guides to himself those who often turn to him and else where said he has shown the signs to a people who are certain. Those who ask God frequently believing in what Quran has said about guidance, miracles, and the guide, I believe they will be shown and be guided by the hands of Imam Mahdi and he will show clear miracles and proofs. Ibrahim asked God to show him clear proofs - show him how to raise the dead, so he can have tranquility. We have the right as well in my view.
The only difference is Imam Mahdi is not in public view, and miracles are not in public view in front of masses.
