Difference between the samā’ (sky) & the ard
Ibn al-Qayyim may Allah have mercy on him said:
“Deeds are not favoured by their outer appearance or their numbers,
but indeed they are favoured by beautifying what is in the heart (ikhlās),
for the two deeds look the same (outwardly) but there can be a difference between them like a difference between the samā’ (sky) & the ard (earth)”
May Allah make us from the mukhlisīn!
