It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him), he said: On the Day of Resurrection, when people will be standing before the Lord of the worlds, Allah Almighty will not let the servants go before asking them about four things: How did you spend your life? In what did you use your body? How did you earn your wealth and in what did you spend it? And how much did you act upon the knowledge you acquired?

Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) said: On the Day of Resurrection, no servant's feet will move until he is asked about four things: In what did he spend his life? In what did he use his body? How did he earn his wealth and where did he spend it? And how much did he act upon the knowledge he acquired?

It is narrated from Laith bin Abi Sulaim: Imam Tawus (may Allah have mercy on him) said to me: Learn knowledge for yourself, because trustworthiness has been lifted from the people.

It is narrated from ‘Imarah bin Mihran that Imam Hasan (may Allah have mercy on him) said: I found such a group that when any worshipper among them would worship, it could not be known from his speech, but they would be recognized by their actions. This is the beneficial knowledge.
