Narrated Abu Bakra:
The Prophet. said, “The biggest of the great sins are: To join others in worship with Allah, to be un –
dutiful to one’s parents, and to give a false witness.” He repeated it thrice, or said, “….a false
statement,” and kept on repeating that warning till we wished he would stop saying it. (See Hadith
