Abdullah ibn Mas’ud, RadhiAllahu Anhu, reported: The Prophet, SallAllahu Alayhi Wa Sallam, said:

لَا حَسَدَ إِلَّا فِي اثْنَتَيْنِ رَجُلٌ آتَاهُ اللَّهُ مَالًا فَسُلِّطَ عَلَى هَلَكَتِهِ فِي الْحَقِّ وَرَجُلٌ آتَاهُ اللَّهُ الْحِكْمَةَ فَهُوَ يَقْضِي بِهَا وَيُعَلِّمُهَا

There is no envy but in two cases: a man whom Allah has given wealth and he spends it rightly, and a man whom Allah has given wisdom and he judges and teaches with it.

Abu Musa, RadhiAllahu Anhu, reported: The Prophet, SallAllahu Alayhi Wa Sallam, said:

إِنَّ مَثَلَ مَا بَعَثَنِيَ اللَّهُ بِهِ عَزَّ وَجَلَّ مِنْ الْهُدَى وَالْعِلْمِ كَمَثَلِ غَيْثٍ أَصَابَ أَرْضًا فَكَانَتْ مِنْهَا طَائِفَةٌ طَيِّبَةٌ قَبِلَتْ الْمَاءَ فَأَنْبَتَتْ الْكَلَأَ وَالْعُشْبَ الْكَثِيرَ يَرْفَعْ وَكَانَ مِنْهَا أَجَادِبُ أَمْسَكَتْ الْمَاءَ فَنَفَعَ اللَّهُ بِهَا النَّاسَ فَشَرِبُوا مِنْهَا وَسَقَوْا وَرَعَوْا وَأَصَابَ طَائِفَةً مِنْهَا أُخْرَى إِنَّمَا هِيَ قِيعَانٌ لَا تُمْسِكُ مَاءً وَلَا تُنْبِتُ كَلَأً فَذَلِكَ مَثَلُ مَنْ فَقُهَ فِي دِينِ اللَّهِ وَنَفَعَهُ بِمَا بَعَثَنِيَ اللَّهُ بِهِ فَعَلِمَ وَعَلَّمَ وَمَثَلُ مَنْ لَمْ يَرْفَعْ بِذَلِكَ رَأْسًا وَلَمْ يَقْبَلْ هُدَى اللَّهِ الَّذِي أُرْسِلْتُ بِهِ

Verily, the parable of the guidance and knowledge that Allah Almighty sent with me is the likeness of rain falling upon the earth. Among them is a good group which receives the water and thus there is abundant growth of herbage and grass. Among them is a barren land which retains the water and thus Allah benefits people from it; they drink from it and graze their animals. And it falls upon another group which is only abysmal; it does not retain water, nor does herbage grow. Such is the parable of one who understands the religion of Allah and benefits from what Allah sent with me; he learns and he teaches. Such is the parable of one who does not raise his head and does not accept the guidance Allah sent with me.

Abu Huraira, RadhiAllahu Anhu, reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, 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.

In another narration, the Prophet, SallAllahu Alayhi Wa Sallam, said:

إِنَّ مِمَّا يَلْحَقُ الْمُؤْمِنَ مِنْ عَمَلِهِ وَحَسَنَاتِهِ بَعْدَ مَوْتِهِ عِلْمًا عَلَّمَهُ وَنَشَرَهُ وَوَلَدًا صَالِحًا تَرَكَهُ وَمُصْحَفًا وَرَّثَهُ أَوْ مَسْجِدًا بَنَاهُ أَوْ بَيْتًا لِابْنِ السَّبِيلِ بَنَاهُ أَوْ نَهْرًا أَجْرَاهُ أَوْ صَدَقَةً أَخْرَجَهَا مِنْ مَالِهِ فِي صِحَّتِهِ وَحَيَاتِهِ يَلْحَقُهُ مِنْ بَعْدِ مَوْتِهِ

Verily, among the good deeds that will join a believer after his death are these: knowledge which he taught and spread, a righteous child he leaves behind, a copy of the Quran he leaves for inheritance, a mosque he has built, a house he built for travelers, a well he has dug, and charity distributed from his wealth while he was alive and well. These deeds will join him after his death.

Abu Qatadah, RadhiAllahu Anhu, reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, said:

خَيْرُ مَا يُخَلِّفُ الرَّجُلُ مِنْ بَعْدِهِ ثَلَاثٌ وَلَدٌ صَالِحٌ يَدْعُو لَهُ وَصَدَقَةٌ تَجْرِي يَبْلُغُهُ أَجْرُهَا وَعِلْمٌ يُعْمَلُ بِهِ مِنْ بَعْدِهِ

The best of what a man leaves behind are three: a righteous child who supplicates for him, ongoing charity the reward of which reaches him, and knowledge that is acted upon after him.

Mu’adh ibn Anas, RadhiAllahu Anhu, reported: The Prophet, SallAllahu Alayhi Wa Sallam, said:

مَنْ عَلَّمَ عِلْمًا فَلَهُ أَجْرُ مَنْ عَمِلَ بِهِ لَا يَنْقُصُ مِنْ أَجْرِ الْعَامِلِ

Whoever imparts knowledge will have the reward of whoever acted upon it, without detracting from the reward of one who acted.

Abu Umamah, RadhiAllahu Anhu, reported: The Messenger of Allah, SallAllahu Alayhi Wa Sallam, said:

فَضْلُ الْعَالِمِ عَلَى الْعَابِدِ كَفَضْلِي عَلَى أَدْنَاكُمْ إِنَّ اللَّهَ وَمَلَائِكَتَهُ وَأَهْلَ السَّمَوَاتِ وَالْأَرَضِينَ حَتَّى النَّمْلَةَ فِي جُحْرِهَا وَحَتَّى الْحُوتَ لَيُصَلُّونَ عَلَى مُعَلِّمِ النَّاسِ الْخَيْرَ

The virtue of the scholar over the worshiper is like my virtue over the least of you. Verily, Allah, his angels, the inhabitants of the heavens and earth, even the ant in his hole and the fish, send blessings upon the one who teaches people what is good.

Fudayl ibn ‘Iyad, may Allah have mercy on him, said:

عَالِمٌ عَامِلٌ مُعَلِّمٌ يُدْعَى كَبِيرًا فِي مَلَكُوتِ السَّمَوَاتِ

A scholar who works in teaching has a high status in the domain of the heavens.

Aisha, RadhiAllahu Anha, reported: The Prophet, SallAllahu Alayhi Wa Sallam, said:

مُعَلِّمُ الْخَيْرِ يَسْتَغْفِرُ لَهُ كُلُّ شَيْءٍ حَتَّى الْحِيتَانُ فِي الْبَحْرِ

Everything seeks forgiveness for the teacher of virtue, even fish in the sea.
