Sheikh Ahmad Kutty, A Senior Lecturer and an Islamic Scholar at the Islamic Institute of Toronto, Ontario, Canada, states the following: “No Muslim can afford to jest or joke about such grave matters. How can anyone be so reckless as to make jokes about Allah and His religion? Such a person should renew the shahadah and ask forgiveness of Allah.
If someone, however, said something unknowingly about matters he had no knowledge of such as the obligation to wear hijab he/she will be excused so long as they had no chance to be exposed to the authentic knowledge of Islam. However, scholars are of the view that there is no excuse for anyone ignoring fundamentals of religion if they are born in a Muslim society. The case, however, is different if they are born in a predominantly non-Muslim milieu where Islamic knowledge is not so common.
It is, however, important for us to know that our words are reckoned either for us or against us. Therefore, it is imperative that they hasten to ask forgiveness of Allah for all sins, major and minor, although Allah has told us in the Qur’an he is not going to take us to task for our slips and unwilful acts of omission or commission. We are however warned against our wilful acts.
Finally, the faithful are taught to practice istighfar (begging Allah for mercy) consistently as many times a day as possible.
May Allah forgive us our trespasses, and may He cleanse us of all our sins, major and minor, outward as well inward-ameen.”
