`AbdurRahman bin Abza said, "Ask Ibn `Abbas about these two Qur'anic Verses: 'Nor kill such life as Allah has made sacred, Except for just cause.' (25.168) "And whoever kills a believer intentionally, his recompense is Hell. (4.93) So I asked Ibn `Abbas who said, "When the Verse that is in Sura-al-Furqan was revealed, the pagans of Mecca said, 'But we have slain such life as Allah has made sacred, and we have invoked other gods along with Allah, and we have also committed fornication.' So Allah revealed:-- 'Except those who repent, believe, and do good-- (25.70) So this Verse was concerned with those people. As for the Verse in Surat-an-Nisa (4-93), it means that if a man, after understanding Islam and its laws and obligations, murders somebody, then his punishment is to dwell in the (Hell) Fire forever." Then I mentioned this to Mujahid who said, "Except the one who regrets (one's crime) . "

A bedouin with unkempt hair came to Allah's Apostle and said, "O Allah's Apostle! Inform me what Allah has made compulsory for me as regards the prayers." He replied: "You have to offer perfectly the five compulsory prayers in a day and night (24 hours), unless you want to pray Nawafil." The bedouin further asked, "Inform me what Allah has made compulsory for me as regards fasting." He replied, "You have to fast during the whole month of Ramadan, unless you want to fast more as Nawafil." The bedouin further asked, "Tell me how much Zakat Allah has enjoined on me." Thus, Allah's Apostle informed him about all the rules (i.e. fundamentals) of Islam. The bedouin then said, "By Him Who has honored you, I will neither perform any Nawafil nor will I decrease what Allah has enjoined on me. Allah's Apostle said, "If he is saying the truth, he will succeed (or he will be granted Paradise).

A bedouin with unkempt hair came to Allah's Apostle and said, "O Allah's Apostle! Tell me what Allah has enjoined on me as regards prayers." The Prophet 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 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 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 Apostle 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.
