Sahih al-Bukhari 6956

Narrated Talha bin ‘Ubaidullah:

A bedouin with unkempt hair came to Allah’s Messenger (ﷺ) and said, “O Allah’s Messenger! Tell me what
Allah has enjoined on me as regards prayers.” The Prophet (ﷺ) said, “You have to offer perfectly the five
(compulsory) prayers in a day and a night (24 hrs.), except if you want to perform some extra optional
prayers.” The bedouin said, “Tell me what Allah has enjoined on me as regards fasting.” The Prophet (ﷺ)
said, “You have to observe fast during the month of Ramadan except if you fast some extra optional
fast.” The bedouin said, “Tell me what Allah has enjoined on me as regard Zakat.” The Prophet (ﷺ) then
told him the Islamic laws and regulations whereupon the bedouin said, “By Him Who has honored
you, I will not perform any optional deeds of worship and I will not leave anything of what Allah has
enjoined on me.” Allah’s Messenger (ﷺ) said, “He will be successful if he has told the truth (or he will enter
Paradise if he said the truth).” And some people said, “The Zakat for one-hundred and twenty camels
is two Hiqqas, and if the Zakat payer slaughters the camels intentionally or gives them as a present or
plays some other trick in order to avoid the Zakat, then there is no harm (in it) for him.
