Is it considered disbelief to stop reciting the Quran to answer a phone call, then resume the recitation? And is it considered disbelief for a person to openly commit sins such as swearing falsely and mocking? And is a single testimony (Shahada) sufficient for him to enter Islam after uttering a word of disbelief, knowing that he prays and fasts?

Firstly: Speaking with foreign women unnecessarily, or with pleasure derived from hearing a woman's voice or her soft speech, is forbidden and constitutes fornication of the tongue and ear. However, if there is a need, the default is permissibility, provided the etiquette of Islamic law is observed.

Secondly: One who interrupts their recitation from the Mushaf due to preoccupation and then returns to it does not commit an act of disbelief by doing so, even if the preoccupation was with a sinful act, unless they intended to belittle the word of Allah.

Thirdly: Swearing falsely is an abomination, and its sin is compounded by laughing along with it. One does not commit an act of disbelief by it unless they intended to ridicule the religion of Allah the Almighty.

Fourthly: Whoever commits an act of disbelief must repent from it and pronounce the two testimonies of faith to re-enter Islam. They are not required to repeat them thereafter, or to pronounce them at the time of committing the act of disbelief. Rather, what is important is their repentance and pronouncement of the two testimonies after having committed that act.
