Allāh's ﷻ generosity is endless. As much as we never tire of sinning, He ﷻ never tires of forgiving. There are some days and nights in which He forgives more – the days of Ramaḍān, the night of ‘Īd, the days of Ḥajj. So ask for yourself, for the Ummati Muḥammad, and to send Sayyidinā al-Mahdī (as).
