Kathir ibn Qays said: I was sitting with AbudDarda' in the mosque of Damascus. A man came to him and said: AbudDarda, I have come to you from the town of the Messenger of Allah ﷺ for a tradition that I have heard you relate from the Messenger of Allah ﷺ. I have come for no other purpose. He said: I heard the Messenger of Allah ﷺ say: If anyone travels on a road in search of knowledge, Allah will cause him to travel on one of the roads of Paradise. The angels will lower their wings in their great pleasure with one who seeks knowledge, the inhabitants of the heavens and the Earth and the fish in the deep waters will ask forgiveness for the learned man. The superiority of the learned man over the devout is like that of the moon, on the night when it is full, over the rest of the stars. The learned are the heirs of the Prophets, and the Prophets leave neither dinar nor dirham, leaving only knowledge, and he who takes it takes an abundant portion.  

كُنْتُ جَالِسًا مَعَ أَبِي الدَّرْدَاءِ فِي مَسْجِدِ دِمَشْقَ فَجَاءَهُ رَجُلٌ فَقَالَ يَا أَبَا الدَّرْدَاءِ إِنِّي جِئْتُكَ مِنْ مَدِينَةِ الرَّسُولِ ﷺ لِحَدِيثٍ بَلَغَنِي أَنَّكَ تُحَدِّثُهُ عَنْ رَسُولِ اللَّهِ ﷺ مَا جِئْتُ لِحَاجَةٍ قَالَ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ سَلَكَ طَرِيقًا يَطْلُبُ فِيهِ عِلْمًا سَلَكَ اللَّهُ بِهِ طَرِيقًا مِنْ طُرُقِ الْجَنَّةِ وَإِنَّ الْمَلاَئِكَةَ لَتَضَعُ أَجْنِحَتَهَا رِضًا لِطَالِبِ الْعِلْمِ وَإِنَّ الْعَالِمَ لَيَسْتَغْفِرُ لَهُ مَنْ فِي السَّمَوَاتِ وَمَنْ فِي الأَرْضِ وَالْحِيتَانُ فِي جَوْفِ الْمَاءِ وَإِنَّ فَضْلَ الْعَالِمِ عَلَى الْعَابِدِ كَفَضْلِ الْقَمَرِ لَيْلَةَ الْبَدْرِ عَلَى سَائِرِ الْكَوَاكِبِ وَإِنَّ الْعُلَمَاءَ وَرَثَةُ الأَنْبِيَاءِ وَإِنَّ الأَنْبِيَاءَ لَمْ يُوَرِّثُوا دِينَارًا وَلاَ دِرْهَمًا وَرَّثُوا الْعِلْمَ فَمَنْ أَخَذَهُ أَخَذَ بِحَظٍّ وَافِرٍ  

The tradition mentioned above has also been transmitted by Abu al-Darda through a different chain of narrators to the same effect from the Holy Prophet ﷺ  

عَنِ النَّبِيِّ ﷺ بِمَعْنَاهُ  

If anyone pursues a path in search of knowledge, Allah will thereby make easy for him a path to paradise; and he who is made slow by his actions will not be speeded by his genealogy.  

قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ رَجُلٍ يَسْلُكُ طَرِيقًا يَطْلُبُ فِيهِ عِلْمًا إِلاَّ سَهَّلَ اللَّهُ لَهُ بِهِ طَرِيقَ الْجَنَّةِ وَمَنْ أَبْطَأَ بِهِ عَمَلُهُ لَمْ يُسْرِعْ بِهِ نَسَبُهُ
