It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Deeds are of seven kinds: two deeds that bring salvation, two deeds that are recompensed with their like, one deed that has a tenfold reward, one deed that has a seven-hundredfold reward, and one deed whose doer's reward no one knows except Allah, the Mighty and Majestic.
As for the two deeds that bring salvation: whoever meets Allah, the Mighty and Majestic, in the state that he worships Him sincerely, not associating anything with Him, Paradise becomes obligatory for him; and whoever meets Allah in the state that he associates something with Him, the Fire becomes obligatory for him. Whoever does an evil deed is recompensed with its like; and whoever intends to do a good deed but does not do it is recompensed with the like of one good deed (these are the two deeds recompensed with their like). Whoever does a good deed is recompensed tenfold; and whoever spends his wealth in the path of Allah, the spending of one dirham is multiplied for him seven hundredfold, and of one dinar seven hundredfold. And fasting is the deed whose doer's reward no one knows except Allah, the Mighty and Majestic."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abdullah bin Dinar (may Allah have mercy on him) except Umar bin Muhammad (may Allah have mercy on him), and Abu Aqil (may Allah have mercy on him) is alone in narrating it."
