حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، قَالَ قَالَ حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ سَمِعْتُ مُعَاوِيَةَ، خَطِيبًا يَقُولُ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏ "‏ مَنْ يُرِدِ الله بِهِ خَيْرًا يُفَقِّهْهُ فِي الدِّينِ، وَإِنَّمَا أَنَا قَاسِمٌ وَالله يُعْطِي، وَلَنْ تَزَالَ هَذِهِ الأُمَّةُ قَائِمَةً عَلَى أَمْرِ الله لاَ يَضُرُّهُمْ مَنْ خَالَفَهُمْ حَتَّى يَأْتِيَ أَمْرُ الله ‏"‌‏.‏

Narrated Muawiya: I heard Allah's Messenger (ﷺ) saying, "If Allah wants to do good to a person, He makes him comprehend the religion. I am just a distributor, but the grant is from Allah. (And remember) that this nation (true Muslims) will keep on following Allah's teachings strictly and they will not be harmed by any one going on a different path till Allah's order (Day of Judgment) is established."

#Sahih al-Bukhari 71
Chapter 13: If Allah Jalla Jalalahu wants to do good to a person, He makes him comprehend (the religion). [The understanding of the Qur'an and As-Sunna (legal ways) of the Prophet (Muhammad (saws))], Book 3: Knowledge

عَنِ ابْنِ عُمَرَ، قَال قَالَ رَسُولُ الله صلى الله عليه وسلم ‏ "‏ مَنِ اقْتَنَى كَلْبًا إِلاَّ كَلْبَ مَاشِيَةٍ أَوْ ضَارِي نَقَصَ مِنْ عَمَلِهِ كُلَّ يَوْمٍ قِيرَاطَانِ ‏"‏ ‏.‏

Ibn Umar (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying: He who keeps a dog other than that meant for watching the herd or for hunting loses every day out of his deeds equal to two qirat.

#Sahih Muslim 1574a
Chapter 10: The command to kill dogs, and its abrogation. The prohibition of keeping dogs, except for hunting, farming, (herding) livestock and the like, Book 22: The Book of Musaqah

عَنْ أُمِّ الْمُؤْمِنِينَ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا، قَالَتْ: قَالَ رَسُولُ الله صلى الله عليه و سلم "مَنْ أَحْدَثَ فِي أَمْرِنَا هَذَا مَا لَيْسَ مِنْهُ فَهُوَ رَدٌّ [رَوَاهُ الْبُخَارِيُّ] ،[وَمُسْلِمٌ] وَفِي رِوَايَةٍ لِمُسْلِمٍ: مَنْ عَمِلَ عَمَلًا لَيْسَ عَلَيْهِ أَمْرُنَا فَهُوَ رَدٌّ".

On the authority of the mother of the faithful, Aisha (ra), who said: The Messenger of Allah (ﷺ) said, “He who innovates something in this matter of ours (i.e., Islam) that is not of it will have it rejected (by Allah).”
[Bukhari & Muslim] In another version in Muslim it reads: “He who does an act which we have not commanded, will have it rejected (by Allah).”
