[5]. Surah Al-Ma'idah [The Table Spread With Food]
Ayat 27. And (O Muhammad [S.A.W.W](P.B.U.H) recite to them (the Jews) the story of the two sons of Adam [Habil (Abel) and Qabil (Cain)] in truth; when each offered a sacrifice (to Allah), it was accepted from the one but not from the other. The latter said to the former: "I will surely kill you. " The former said: "Verily, Allah accepts only from those who are Al-Muttaqun [the pious].
Hadith
Ibn Mas`ud (May Allah be pleased with him) reported: The Prophet [S.A.W.W](P.B.U.H) said, "The first son of Adam* takes a share of the guilt of every one who murders another wrongfully because he was the initiator of committing murder".
[Al-Bukhari and Muslim].
Lesson : as mentioned above in Surah Al-Ma'idah Ayat 27 * The son of Adam in the Hadith is said to be Qabil. Allah tells us about his story in Surat Al-Ma'idah (The Table spread with Food). Verses 27-31.
This Hadith gives us an idea how serious is the crime of initiating an evil which is followed by others. One who initiates an evil would be sinful for all those who follow him in that crime till the Day of Resurrection. The safest course, therefore, is that one should abstain from heresy and stick to obedience only.
