Virtues of Acquiring Islamic Knowledge

Mu’awiyah reported:
The Messenger of Allah, peace and blessings be upon him, said:

If Allah intends goodness for someone, he gives him understanding of the religion. 
(Ṣaḥiḥ al-Bukhari; 71)

Abu Darda reported:
The Messenger of Allah, peace and blessings be upon him, said:

وَإِنَّ الْمَلَائِكَةَ لَتَضَعُ أَجْنِحَتَهَا رِضًا لِطَالِبِ الْعِلْمِ وَإِنَّ الْعَالِمَ لَيَسْتَغْفِرُ لَهُ مَنْ فِي السَّمَوَاتِ وَمَنْ فِي الْأَرْضِ وَالْحِيتَانُ فِي جَوْفِ الْمَاءِ وَإِنَّ فَضْلَ الْعَالِمِ عَلَى الْعَابِدِ كَفَضْلِ الْقَمَرِ لَيْلَةَ الْبَدْرِ عَلَى سَائِرِ الْكَوَاكِبِ وَإِنَّ الْعُلَمَاءَ وَرَثَةُ الْأَنْبِيَاءِ وَإِنَّ الْأَنْبِيَاءَ لَمْ يُوَرِّثُوا دِينَارًا وَلَا دِرْهَمًا وَرَّثُوا الْعِلْمَ فَمَنْ أَخَذَهُ أَخَذَ بِحَظٍّ وَافِرٍ

Verily, the angels lower their wings for the seeker of knowledge. The inhabitants of the heavens and earth, even the fish in the depths of the water, seek forgiveness for the scholar. The virtue of the scholar over the worshiper is like the superiority of the moon over the stars. The scholars are the inheritors of the Prophets. They do not leave behind gold or silver coins, but rather they leave behind knowledge. Whoever has taken hold of it has been given an abundant share.
(Sunan Abu Dawud; 3641)

Abu Huraira reported:
The Messenger of Allah, peace and blessings be upon him, said:

إِذَا مَاتَ الْإِنْسَانُ انْقَطَعَ عَنْهُ عَمَلُهُ إِلَّا مِنْ ثَلَاثَةٍ إِلَّا مِنْ صَدَقَةٍ جَارِيَةٍ أَوْ عِلْمٍ يُنْتَفَعُ بِهِ أَوْ وَلَدٍ صَالِحٍ يَدْعُو لَهُ

When the human being dies, his deeds end except for three: ongoing charity, beneficial knowledge, or a righteous child who prays for him.
(Ṣaḥih Muslim; 16310)
