Narrated 'Amr bin 'Auf al-Muzani (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "Reconciliation is permissible between Muslims, except one which makes unlawful something which is lawful, or makes lawful something which is unlawful; and Muslims must abide by their conditions (which they have made), except for a condition which makes unlawful something which is lawful, or makes lawful something which is unlawful." [at-Tirmidhi reported it and graded it Sahih (authentic)] . However, the Hadith scholars criticized him (for grading this Hadith as Sahih) because the narration of Kathir bin 'Abdullah bin 'Amr bin 'Auf is weak. It is as though at-Tirmidhi considered it (reliable) due to its many chains of narration. Ibn Hibban declared the aforesaid Hadith to be Sahih (authentic) from the narration of Abu Hurairah (RA).

Narrated Abu Hurairah (RA): The Prophet ( صلی اللہ علیہ وسلم ) said: "One must not prevent his neighbor from fixing a wooden peg in his wall." Abu Hurairah (RA) then said, "Why do I see you turning away (averse to this Sunnah)? I swear by Allah that I will always narrate it to you." [Agreed upon] .

Narrated Abu Humaid as-Sa'idi (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "It is not lawful for a person to take his brother's stick except if he is pleased with such." [Ibn Hibban and al-Hakim reported it in their two Sahih books] .
