It was narrated that Hanzalah said: “I saw Tawus pass by the Corner. If he saw it was crowded, he would pass by and he would not push his way in. And if he saw it was free, he would kiss it three times, then he said: ‘I saw Ibn ‘Abbas doing that. Ibn ‘Abbas said: I saw ‘Umar bin Al-Khattab doing that, then he said: You are just a stone that can neither cause harm or bring benefit; were it not that I saw the Messenger of Allah صلی اللہ علیہ وآلہ وسلم kissing you I would not have kissed you.’ Then ‘Umar said: ‘I saw the Messenger of Allah صلی اللہ علیہ وآلہ وسلم doing that.” (Sahih)
