I had two times when I would enter upon the Messenger of Allah ﷺ, one by night and one by day. Whenever I came in while he was praying, he would clear his throat to signal me.One night I went to him and he said, "Do you know what the angel told me tonight? I was praying when I heard a rustling in the house, so I went out and there was Jibreel . He said, 'I have been waiting for you all this night. There is a dog in your house, so I could not enter. We do not enter a house in which there is a dog, a person in a state of major ritual impurity, or an image.'"
حدثنا أبو بكر بن عياش حدثنا مغيرة بن مقسم حدثنا الحارث العكلي عن عبد الله بن نجي قال
كان لي من رسول الله ﷺ مدخلان بالليل والنهار وكنت إذا دخلت عليه وهو يصلي تنحنح فأتيته ذات ليلة فقال أتدري ما أحدث الملك الليلة كنت أصلي فسمعت خشفة في الدار فخرجت فإذا جبريل عليه السلام فقال ما زلت هذه الليلة أنتظرك إن في بيتك كلبا فلم أستطع الدخول وإنا لا ندخل بيتا فيه كلب ولا جنب ولا تمثال
Its chain of transmission is daif due to disconnection. Abdullah bin Naji did not hear from Ali, rather he narrates from his father, from Ali, as already mentioned at 570. This hadith is a longer version of that one, but there Harith Ukayli narrates from Abu Zura bin Amr bin Jareer, from Abdullah bin Naji, while here Harith narrates from Abdullah bin Naji directly. Harith narrates from both of them, but it is the same hadith, so perhaps Abu Bakr bin Ayyash erred in omitting Abu Zura. Bukhari alluded to this hadith in Tarikh al-Kabir 121/2/4, in the entry on Naji, the father of Abdullah. Nasai narrated part of it, 178/1, from Muhammad bin Ubayd, and likewise Ibn Majah, 208/2, from Abu Bakr bin Abu Shayba, both of them from Abu Bakr bin Ayyash. See also 598.Abu Bakr bin Ayyash was deemed trustworthy by Ibn Main and others. Ahmad said, "He is trustworthy, though he might sometimes err." Ibn Hibban said, "He was among the devout, precise memorizers of hadith." Yahya Qattan and Ali bin Madini held a poor opinion of him, because when he grew old his memory weakened, so he would make mistakes when narrating. Yet making mistakes and memorizing are two things inseparable from human nature, so whoever does not do this excessively does not deserve to have his hadith discarded, once his integrity has already been established.Khashfah, with a fatha on the kha and a sakin on the shin, means a sound or a movement. It has also been said to mean the sound itself, while with a fatha on the shin it means the movement. It has also been said that both readings carry the same meaning. See also 132, 647.
