Messenger of Allah ﷺ addressed us and said: O people, Allah has made Hajj obligatory for you; so perform Hajj. Thereupon a person said: Messenger of Allah, (is it to be performed) every year? He (the Holy Prophet) kept quiet, and he repeated (these words) thrice, whereupon Messenger of Allah ﷺ said: If I were to say" Yes," it would become obligatory (for you to perform it every year) and you would not be able to do it. Then he said: Leave me with what I have left to you, for those who were before you were desroyed because of excessive questioning, and their opposition to their apostles. So when I command you to do anything, do it as much as it lies in your power and when I forbid you to do anything, then abandon it. (Using translation from Muslim 1337)   

خَطَبَنَا رَسُولُ اللهِ ﷺ فَقَالَ أَيُّهَا النَّاسُ قَدْ فُرِضَ عَلَيْكُمُ الْحَجُّ فَحُجُّوا فَقَالَ رَجُلٌ أَكُلَّ عَامٍ يَا رَسُولَ اللهِ؟ فَسَكَتَ حَتَّى قَالَهَا ثَلَاثًا فَقَالَ رَسُولُ اللهِ ﷺ لَوْ قُلْتُ نَعَمْ لَوَجَبَتْ وَلَمَا اسْتَطَعْتُمْ ثُمَّ قَالَ ذَرُونِي مَا تَرَكْتُكُمْ فَإِنَّمَا هَلَكَ مَنْ كَانَ قَبْلَكُمْ بِكَثْرَةِ سُؤَالِهِمْ وَاخْتِلَافِهِمْ عَلَى أَنْبِيَائِهِمْ وَإِذَا أَمَرْتُكُمْ بِشَيْءٍ فَأْتُوا مِنْهُ مَا اسْتَطَعْتُمْ وَإِذَا نَهَيْتُكُمْ عَنْ شَيْءٍ فَدَعُوهُ  

[Machine] I heard Jabir bin Abdullah say, "We have declared the companions of the Messenger of Allah ﷺ as pure by performing the Hajj sincerely." Then he mentioned the Hadith and said, "Suraqah bin Malik asked, 'O Messenger of Allah, is this permission for our year only or forever?' He said, 'No, it is forever.'"  

سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللهِ يَقُولُ أَهْلَلْنَا أَصْحَابَ رَسُولِ اللهِ ﷺ بِالْحَجِّ خَالِصًا فَذَكَرَ الْحَدِيثَ قَالَ فِيهِ فَقَالَ سُرَاقَةُ بْنُ مَالِكٍ مُتْعَتُنَا هَذِهِ يَا رَسُولَ اللهِ لِعَامِنَا هَذَا أَمْ لِلْأَبَدِ؟ قَالَ لَا بَلْ لِلْأَبَدِ  

[Machine] The Prophet ﷺ delivered a sermon and said, "O people, Allah has made Hajj obligatory upon you." Al-Aqra' bin Habis stood up and asked, "O Messenger of Allah, is it obligated every year?" He replied, "If I were to say yes, it would become obligatory and you would not be able to fulfill it every year. However, whoever performs it voluntarily, it will be counted as a means of reward." Sufyan bin Husayn and Muhammad bin Abi Hafsah narrated this from Az-Zuhri, who learned it from Abu Sinan Ad-Dawli. In a narration by Jabir bin Abdullah, Suraqah bin Malik asked, "O Messenger of Allah, is this (taking slaves as captives) a temporary dispensation for us or is it lawful forever?" He answered, "No, rather it is lawful forever."  

خَطَبَنَا رَسُولُ اللهِ ﷺ قَالَ يَا أَيُّهَا النَّاسُ إِنَّ اللهَ كَتَبَ عَلَيْكُمُ الْحَجَّ فَقَامَ الْأَقْرَعُ بْنُ حَابِسٍ فَقَالَ أَفِي كُلِّ عَامٍ يَا رَسُولَ اللهِ؟ قَالَ لَوْ قُلْتُهَا لَوَجَبَتْ وَلَوْ وَجَبَتْ لَمْ تَعْمَلُوا بِهَا وَلَمْ تَسْتَطِيعُوا أَنْ تَعْمَلُوا بِهَا الْحَجُّ مَرَّةٌ فَمَنْ زَادَ فَتَطَوُّعٌ تَابَعَهُ سُفْيَانُ بْنُ حُسَيْنٍ وَمُحَمَّدُ بْنُ أَبِي حَفْصَةَ عَنِ الزُّهْرِيِّ عَنْ أَبِي سِنَانٍ وَقَالَ عَقِيلٌ عَنِ الزُّهْرِيِّ عَنْ سِنَانٍ وَهُوَ أَبُو سِنَانٍ الدُّؤَلِيُّ وَفِي حَدِيثِ جَابِرِ بْنِ عَبْدِ اللهِ أَنَّ سُرَاقَةَ بْنَ مَالِكٍ قَالَ مُتْعَتُنَا هَذِهِ يَا رَسُولَ اللهِ لِعَامِنَا هَذَا أَمْ لِلْأَبَدِ؟ قَالَ لَا بَلْ لِلْأَبَدِ
