In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Shaikh Zayd Bin Haadi Al-Madkhali [rahimahullaah] said: ‘When a believer reads this Ayah [i.e. يَرْفَعِ اللَّهُ الَّذِينَ آمَنُوا مِنْكُمْ وَالَّذِينَ أُوتُوا الْعِلْمَ دَرَجَاتٍ ۚ وَاللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ -Allaah will exalt in degree those of you who believe, and those who have been granted knowledge.  And Allaah is well-Acquainted with what you do] and (the other Aayaat) similar to it, he will love knowledge; seek after it and keep in contact with its people; act upon it, call the people to it and make them have a desire for it. So he benefits himself and Allaah benefits others by way of it.  Thus he follows the Prophet [sallal-laahu-alayhi-sallam] in his Dawah and conduct. [Source: ‘Nuzhatul Qaaree Fee Sharh Kitaab Al-Ilm Min Saheeh Al-Bukhaari’ page: 15]
