To protect one‘s tongue

Narrated Sahl bin Sa'd:

Allah's Apostle ﷺ said, "Whoever can guarantee (the chastity of) what is between his two jaw-bones and what is between his two legs (i.e. his tongue and his private parts), I guarantee Paradise for him."

حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي بَكْرٍ الْمُقَدَّمِيُّ، حَدَّثَنَا عُمَرُ بْنُ عَلِيٍّ، سَمِعَ أَبَا حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ، عَنْ رَسُولِ اللَّهِ ﷺ قَالَ " مَنْ يَضْمَنْ لِي مَا بَيْنَ لَحْيَيْهِ وَمَا بَيْنَ رِجْلَيْهِ أَضْمَنْ لَهُ الْجَنَّةَ ".

Narrated Abu Huraira:

Allah's Apostle ﷺ said, "Whoever believes in Allah and the Last Day should talk what is good or keep quiet, and whoever believes in Allah and the Last Day should not hurt (or insult) his neighbor;
and whoever believes in Allah and the Last Day, should entertain his guest generously."

حَدَّثَنِي عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا، أَوْ لِيَصْمُتْ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلاَ يُؤْذِ جَارَهُ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ ".

Narrated Abu Shuraih Al-Khuza'i:

My ears heard and my heart grasped (the statement which) the Prophet ﷺ said, "The period for keeping one's guest is three days (and don't forget) his reward." It was asked, "What is his reward?" He said, "In the first night and the day he should be given a high class quality of meals;
and whoever believes in Allah and the Last Day, should entertain his guest generously;
and whoever believes in Allah and the Last Day should talk what is good (sense) or keep quiet."

حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا لَيْثٌ، حَدَّثَنَا سَعِيدٌ الْمَقْبُرِيُّ، عَنْ أَبِي شُرَيْحٍ الْخُزَاعِيِّ، قَالَ سَمِعَ أُذُنَاىَ، وَوَعَاهُ، قَلْبِي النَّبِيَّ ﷺ يَقُولُ " الضِّيَافَةُ ثَلاَثَةُ أَيَّامٍ جَائِزَتُهُ ". قِيلَ مَا جَائِزَتُهُ قَالَ " يَوْمٌ وَلَيْلَةٌ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا، أَوْ لِيَسْكُتْ ".

Narrated Abu Huraira:

That he heard Allah's Apostle saying, "A slave of Allah may utter a word without thinking whether it is right or wrong, he may slip down in the Fire as far away a distance equal to that between the east."

حَدَّثَنِي إِبْرَاهِيمُ بْنُ حَمْزَةَ، حَدَّثَنِي ابْنُ أَبِي حَازِمٍ، عَنْ يَزِيدَ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ، عَنْ عِيسَى بْنِ طَلْحَةَ التَّيْمِيِّ، عَنْ أَبِي هُرَيْرَةَ، سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ " إِنَّ الْعَبْدَ لَيَتَكَلَّمُ بِالْكَلِمَةِ مَا يَتَبَيَّنُ فِيهَا، يَزِلُّ بِهَا فِي النَّارِ أَبْعَدَ مِمَّا بَيْنَ الْمَشْرِقِ ".
