A man called Hazrat Mahdi (as) will come at a time when systems have changed and his benevolence will be plentiful and beautiful. (Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir az-Zaman, p. 14)
He will come at a time when corruption has appeared and his benevolence will be unconditional. (Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-Muntadhar, p. 24)
