taqwa
64-وعن أبي جعفر (ع) قال لو كانت ذنوب المؤمن مثل رمل عالج ومثل زبد البحر لغفرها اله له، فلا تجتروا
64. It has been reported that Abu Ja'far (a.s) said: If the sins of a believer were as much as the sand in the desert or the froth of the sea, Allah would forgive them all; but do not become bold (in sinning, mistaking His Mercy for weakness).
