Hawzah News Agency - The merciful prophet of Islam (peace and blessings of God be upon him and his household) says:
.العِلمُ خَزائنُ ومَفاتِيحُهُ السُّؤالُ، فَاسألُوا رَحِمَكُمُ اللَّهُ فإنّهُ يُؤجَرُ أربَعةٌ : السائلُ ، والمُتَكلِّمُ ، والمُستَمِعُ ، والمُحِبُّ لَهُم
'Knowledge is a treasury, the key to which is the question, so ask and Allah will have mercy on you for verily four people are rewarded [for that question]: the questioner, the speaker, the listener, and the one that admires them.'
