Allah
The Almighty enjoins us to remember Him frequently and perform good deeds
because forgetfulness is a disease that leads to neglecting virtuous deeds.
Allaah The Almighty says:
{وَلَقَدْ عَهِدْنَا إِلَىَ آدَمَ مِن قَبْلُ
فَنَسِيَ وَلَمْ نَجِدْ لَهُ عَزْماً }
'Translated'
{And We had already taken a promise from Adam before, but he forgot; and We
found not in him determination} [Taha: 115]. One's good deeds should be
based on one's belief in Allaah The Almighty, and we must frequently remind
ourselves of the reward for righteous deeds which encourages us to perform
them.
