Good deed is a Key to Paradise

Aisha r.a reported: The Messenger of Allah, peace and blessings be upon him, said, “Be deliberate in worship, draw near to Allah, and give glad tidings. Verily, none of you will enter Paradise because of his deeds alone.”

They said, “Not even you, O Messenger of Allah?” The Prophet said, “Not even me, unless Allah grants me mercy from himself. Know that the most beloved deed to Allah is that which is done regularly even if it is small.”
