Hazrat Saeed bin Musayyib narrates that Ibrahim was the first person who hosted a guest, and the first person who trimmed the moustache, and cut his nails, and cleaned the hair of the private parts, and the first person who performed circumcision, and the first person who saw white hair. So he said: O my Lord! What is this thing? Allah, the Lord of Honor, said: This is dignity and respect. He said: O Lord! Increase my dignity.
