And Abraham instructed his sons [to do the same] and [so did] Jacob, [saying], "O my sons, indeed Allāh has chosen for you this religion, so do not die except while you are Muslims."
As for the hadiths, among them is the following:
حديث زيد بن أرقم - ﵁ - الَّذِي سبق في بَابِ إكرام أهْلِ بَيْتِ رسول الله - ﷺ - قَالَ: قَامَ رسول الله - ﷺ - فِينَا خَطِيبًا، فَحَمِدَ الله، وَأثْنَى عَلَيْهِ، وَوَعَظَ وَذَكَّرَ، ثُمَّ قَالَ: «أمَّا بَعْدُ، ألاَ أيُّهَا النَّاسُ، إنَّمَا أنَا بَشَرٌ يُوشِكُ أَنْ يَأتِيَ رَسُولُ رَبِّي فَأُجِيبَ، وَأنَا تَارِكٌ فِيكُمْ ثَقَلَيْنِ، أوَّلَهُمَا: كِتَابُ اللهِ، فِيهِ الْهُدَى وَالنُّورُ، فَخُذُوا بِكِتَابِ اللهِ وَاسْتَمْسِكُوا بِهِ»، فَحَثَّ عَلَى كِتَابِ اللهِ، وَرَغَّبَ فِيهِ، ثُمَّ قَالَ: «وَأَهْلُ بَيْتِي، أذَكِّرُكُمُ اللهَ في أهْلِ بَيْتِي». رواه مسلم، وَقَدْ سَبَقَ بِطُولِهِ.
The hadith of Zayd ibn Arqam (may Allah be pleased with him), which came earlier in the chapter on honouring the household of the Messenger of Allah (peace and blessings be upon him): He said: The Messenger of Allah (peace and blessings be upon him) stood among us to deliver an address. He praised Allah and extolled Him, and admonished and reminded, then said: "To proceed: O people, I am only a human being, and soon the messenger of my Lord will come and I shall answer. I am leaving among you two weighty things: the first of them is the Book of Allah, in which is guidance and light, so take hold of the Book of Allah and cling fast to it." So he urged adherence to the Book of Allah and encouraged people towards it. Then he said: "And the people of my household: I remind you of Allah regarding the people of my household." Muslim narrated it, and it has already come in full.
وعن أَبي سليمان مالِك بن الحُوَيْرِثِ - ﵁ - قَالَ: أَتَيْنَا رسولَ الله - ﷺ - وَنَحْنُ شَبَبَةٌ مُتَقَارِبُونَ، فَأقَمْنَا عِنْدَهُ عِشْرِينَ لَيْلَةً، وَكَانَ رسولُ الله - ﷺ - رَحِيمًا رَفيقًا، فَظَنَّ أنّا قد اشْتَقْنَا أهْلَنَا، فَسَألَنَا عَمَّنْ تَرَكْنَا مِنْ أهْلِنَا، فَأخْبَرْنَاهُ، فَقَالَ: «ارْجِعُوا إِلَى أهْلِيكُمْ، فَأقِيمُوا فِيهمْ، وَعَلِّمُوهُم وَمُرُوهُمْ، وَصَلُّوا صَلاَةَ كَذَا فِي حِيْنِ كَذَا، وَصَلُّوا كَذَا في حِيْنِ كَذَا، فَإذَا حَضَرَتِ الصَّلاَةُ فَلْيُؤَذِّنْ لَكُمْ أحَدُكُمْ وَلْيَؤُمَّكُمْ أكْبَرُكُمْ». متفقٌ عَلَيْهِ. زاد البخاري في رواية لَهُ: «وَصَلُّوا كَمَا رَأيْتُمُونِي أُصَلِّي». وَقَوْلُه: «رحِيمًا رَفِيقًا» رُوِيَ بِفاءٍ وقافٍ، وَرُوِيَ بقافينِ.
On the authority of Abu Sulayman Malik ibn al-Huwayrith (may Allah be pleased with him), who said: We came to the Messenger of Allah (peace and blessings be upon him) while we were young men close in age, and we stayed with him for twenty nights. The Messenger of Allah (peace and blessings be upon him) was merciful and gentle, and he supposed that we had grown homesick for our families. So he asked us about those we had left behind from our families, and we informed him. He said: "Return to your families, stay among them, teach them and instruct them. Pray such-and-such a prayer at such-and-such a time, and pray such-and-such at such-and-such a time; and when the prayer is due, let one of you give the call to prayer for you, and let the eldest of you lead you." Agreed upon. Al-Bukhari added in a narration of his: "And pray as you have seen me pray." His words "merciful and gentle" (raḥīman rafīqan) were narrated with an f and a q, and were also narrated with two q's.
وعن عمرَ بن الخطاب - ﵁ - قَالَ: اسْتأذَنْتُ النَّبيَّ - ﷺ - في العُمْرَةِ، فَأذِنَ، وقال: «لاَ تَنْسَانَا يَا أُخَيَّ مِنْ دُعَائِكَ» فقالَ كَلِمَةً ما يَسُرُّنِي أنَّ لِي بِهَا الدُّنْيَا. وفي رواية قَالَ: «أشْرِكْنَا يَا أُخَيَّ في دُعَائِكَ». رواه أَبُو داود والترمذي، وقال: «حديث حسن صحيح».
On the authority of Umar ibn al-Khattab (may Allah be pleased with him), who said: I sought the permission of the Prophet (peace and blessings be upon him) to perform the lesser pilgrimage, and he gave permission and said: "Do not forget us, my dear brother, in your supplication." He spoke a word with which I would not be pleased to have the whole world in its place. In another narration he said: "Include us, my dear brother, in your supplication." Abu Dawud and al-Tirmidhi narrated it, and he said: "A good and sound hadith."
وعن سالم بنِ عبدِ الله بنِ عمر: أنَّ عبدَ اللهِ بن عُمَرَ ﵄، كَانَ يَقُولُ للرَّجُلِ إِذَا أرَادَ سَفَرًا: ادْنُ مِنِّي حَتَّى أُوَدِّعَكَ كَمَا كَانَ رسولُ الله - ﷺ - يُوَدِّعُنَا، فَيَقُولُ: «أَسْتَوْدِعُ اللهَ دِينَكَ، وَأمَانَتَكَ، وَخَواتِيمَ عَمَلِكَ». رواه الترمذي، وقال: «حديث حسن صحيح».
On the authority of Salim ibn Abdullah ibn Umar: that Abdullah ibn Umar (may Allah be pleased with them both) used to say to a man when he intended to travel: "Come close to me so that I may bid you farewell, just as the Messenger of Allah (peace and blessings be upon him) used to bid us farewell." Then he would say: "I entrust to Allah your religion, your trust, and the final outcomes of your deeds." Al-Tirmidhi narrated it, and he said: "A good and sound hadith."
وعن عبدِ الله بن يزيدَ الخطْمِيِّ الصحابيِّ - ﵁ - قَالَ: كَانَ رسولُ الله - ﷺ - إِذَا أرَادَ أَنْ يُوَدِّعَ الجَيشَ، قَالَ: «أسْتَوْدِعُ اللهَ دِينَكُمْ، وَأمَانَتَكُمْ، وَخَواتِيمَ أعْمَالِكُمْ» حديث صحيح، رواه أَبُو داود وغيره بإسناد صحيح.

وعن أنسٍ - ﵁ - قَالَ: جَاءَ رَجُلٌ إِلَى النبي - ﷺ - فَقَالَ: يَا رسولَ الله، إنّي أُرِيدُ سَفَرًا، فَزَوِّدْنِي، فَقَالَ: «زَوَّدَكَ الله التَّقْوَى» قَالَ: زِدْنِي قَالَ: «وَغَفَرَ ذَنْبَكَ» قَالَ: زِدْنِي، قَالَ: «وَيَسَّرَ لَكَ الْخَيْرَ حَيْثُمَا كُنْتَ». رواه الترمذي ، وقال: «حديث حسن».
On the authority of Anas (may Allah be pleased with him), who said: A man came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah, I intend to travel, so provide me with provision."

He said: "And may He make good easy for you wherever you may be." Al-Tirmidhi narrated it, and he said: "A good hadith."
