PERSISTENT QUESTIONING H 1298 "The Messenger of Allah, praise and peace be upon him, addressed us saying, 'O people, Allah has made the Pilgrimage obligatory for you, so you should perform it.' A man asked, 'O Messenger of Allah, praise and peace be upon him, is it obligatory every year?' The Messenger of Allah, praise and peace be upon him, remained silent and the man asked his question three times. Then the Prophet, praise and peace be upon him, commented, 'If I had said yes, it would have become obligatory and you could not afford to do so.' Then he added, 'Leave me when I do not comment about something. There were some people before you that were ruined by their habit of asking too many questions and differing with their Prophets. Therefore, when I direct you to do something carry out my direction as far as you are able, but when I forbid anything to you leave it alone altogether.'" R 1298 Muslim with a chain up to Abu Hurairah who related that the Messenger of Allah, praise and peace be upon him, said this.
1272- وعن أَبي هريرة رضي الله عنه ، قَالَ : خَطَبَنَا رسولُ اللهِ صلى الله عليه وآله وسلم ، فَقَالَ : "أيُّهَا النَّاسُ ، قَدْ فَرَضَ اللهُ عَلَيْكُم الحَجَّ فَحُجُّوا" فَقَالَ رَجُلٌ : أكُلَّ عَامٍ يَا رَسولَ اللهِ ؟ فَسَكَتَ ، حَتَّى قَالَهَا ثَلاثاً . فَقَالَ رسولُ الله صلى الله عليه وآله وسلم : "لَوْ قُلْتُ نَعَمْ لَوَجَبَتْ ، وَلَمَا اسْتَطَعْتُمْ" ثُمَّ قَالَ : "ذَرُوني مَا تَرَكْتُكُمْ ؛ فَإنَّمَا هَلَكَ مَنْ كَانَ قَبْلَكُمْ بِكَثْرَةِ سُؤالِهِمْ ، وَاخْتِلاَفِهِمْ عَلَى أنْبِيَائِهِمْ ، فَإذَا أمَرْتُكُمْ بِشَيءٍ فَأتُوا مِنْهُ مَا اسْتَطَعْتُمْ ، وَإِذَا نَهَيْتُكُمْ عَن شَيْءٍ فَدَعُوهُ" رواه مسلم .
