This one? I've never heard anyone claiming that it was weak..

Anâs (Radiallâhu anhu) states that he heard Rasulullah (Sallallâhu alahi wasallam) ) saying that Allâh (azza wajal) said,

"O son of Adam, as long as you supplicate to me and have hope in Me, I will forgive you whatever the sin be and I will not bother. O son of Adam, if your sins reach the clouds in the sky and you seek forgiveness, I will forgive you and I will not bother. O son of Adam, if you come to Me with so many sins that they fill the earth, and you meet Me without having ascribed partners to Me, I will forgive you with the same great amount of forgiveness."

(Tirmidhi)
