"Whoever brings a good deed, he shall have ten like it, and whoever brings an evil deed, he shall be recompensed only with the like of it, and they shall not be dealt with unjustly."

"Deeds without sincerity are like a traveler who carries dirt in his water-jug. The carrying of it burdens him and it brings no benefit."

Al-Hasan Al-Basri (may Allah have mercy upon him) said:

“Almighty Allah has not set a deadline for a believer’s having to do good deeds, except death.”

Then he recited Almighty Allah’s words: And serve thy Lord till the inevitable (death) cometh unto thee (Al-Hijr 15:99)
