A companion prayed 2 units AFTER fajr jamaat before sunrise. this is reported by Abu Dawood, where it says, “and the Messenger of Allaah (peace and blessings of Allaah be upon him) remained silent.” And ‘Ata’ ibn Abi Rabaah narrated that a man of the Ansaar said: “He did not say anything to him.” Al-‘Iraaqi said: its isnaad is hasan. And a version narrated by Ibn Abi Shaybah says: “He did not tell him to do that or tell him not to do it.” And a version narrated by Ibn Hibbaan says: “he did not denounce him.” The reports explain one another.
This silence is taken as affirmation in uloom ul hadith.
The smile of prophet is also taken as affirmation. This information is based on Allahs fingers text given by a jewish woman to aisha and the prophet smiled.
Based on above information i Searched in a internet search engine and failed to find answers.
In a discussion, 2 people were discussing buraq and flying horses. And it was metioned sulayman had flying horses and buraq is neither a horse nor does it fly. Then hadith of prophet laughing such that his molar were visible when aisha said sulayman had flying horses was mentioned.
A third person who read the above hadith said laughing negates flying horses of sulayman.
Hence the question arose which actions of prophet say his affirmation?
