Did you know there is a special salat, aside from the regular five and their nawaafil, that brings great forgiveness from Allah? It is called Salat-ut-Tasbeeh.

There are certain times dua (supplication) is more likely to be accepted by Allah (SWT) as mentioned by Prophet (peace and blessings of Allah be upon him). These times are as follows: 

1. The Last Third Of The Night

Abu Hurairah (RA) narrated that Allah’s Messenger (peace and blessings of Allah be upon him) said: 'In the last third of every night our Rabb (Cherisher and Sustainer) (Allah (SWT)) descends to the lowermost heaven and says; "Who is calling Me, so that I may answer him? Who is asking Me so that may I grant him? Who is seeking forgiveness from Me so that I may forgive him?"' [Sahih al-Bukhari]
