Whosoever Allah blesses with knowledge then he recognises and acknowledges the blessing of Allah upon him and he says just as the Angels and the Prophets said:
They (angels) said: “Glory be to You, we have no knowledge except what you have taught us. Verily, it is You, the All-Knower, the All-Wise.”
And he ceases talking about that which he does not know. For indeed knowledge is the greatest of blessings and (the slave) gives thanks for this blessing by recognising and acknowledging Allah with it.
And he praises Him by teaching it (knowledge) and teaching the ignorant and stopping upon that which the slave has learnt, and remaining silent about what he hasn’t learnt.
