Every Nafil prayed is the Reward of praying a Fard Salaah!
In this most blessed month of Ramadhan all good deeds are multiplied. Every Nafil one prays one will gain the reward of a fard Salaah!
The Prophet peace be upon him said: “Whoever draws near to Allaah during it (Ramadaan) with a single characteristic from the characteristics of (voluntary) goodness, he is like whoever performs an obligatory act in other times. And whoever performs an obligatory act during it, he is like whoever performed seventy obligatory acts in other times.” – Sahih Ibn Khuzaymah, no. 1887.
So in these last few days of Ramadan let us pray as many Nafils as we can for this Ramadan may be our last and on the day of judgement we will be BEGGING for JUST one good deed but we will not be able to get it!!!
