Hadith Narrated By Abdullah bin Amr bin Al Aas

A man came to the Prophet (peace_be_upon_him) and asked him: Messenger of Allah, how is the ablution (to performed)? He (the Prophet) then called for water in a vessel and washed his hands up to the wrists three times, then washed his face three times, and washed his forearms three times. He then wiped his head and inserted both his index fingers in his ear-holes; he wiped the back of his ears with his thumbs and the front of his ears with the index fingers. He then washed his feet three times. Then he said: This is how ablution should be performed. If anyone does more or less than this, he has done wrong and transgressed, or (said) transgressed and done wrong.

The Apostle of Allah (peace_be_upon_him) said: Command your children to pray when they become seven years old, and beat them for it (prayer) when they become ten years old; and arrange their beds (to sleep) separately.

A man said: Apostle of Allah, the mu'adhdhins excel us. The Apostle of Allah (peace_be_upon_him) said: Say (the same words) as they say, and when you come to the end, make a petition and that will be granted to you.

The Prophet (peace_be_upon_him) said: When the Imam completes the prayer and sits (for reciting tashahhud), and then becomes defiled (i.e. his ablution becomes void) before he speaks (to someone), his prayer becomes complete. And those who prayed behind him also complete the prayer.

I saw the Apostle of Allah (peace_be_upon_him) praying both barefooted and wearing sandals.
