Allah praises time from Asr to Maghrib, especially if gathering of dhikr. Reward - angels gather, Allah's mercy, peace in the heart, reward to dead relatives, Allah's praise to the angels. If begin Ramadhan good, so will end. With this reward, mercy, save from hell, from grave, make life easy, release from debt, test of children etc. All from Allah's dhikr - don't just expect you'll get all of this without dhikr. Make schedule in Ramadhan that includes these dhikr gatherings - they are rare, so value them
