Do my statements to a person—"You're speaking dirty words," when he asked me to play religious lectures, and "If it starts with music," upon hearing the sound of religious advice—count as mocking and insulting the religion?

Phrases that outwardly appear to mock religion can be interpreted in another way if the speaker did not intend such mockery. Scholars have explicitly stated that one who utters words that could indicate apostasy or something else is not to be declared an apostate for that. It is stated in Nazm Nawāzil al-Alawī: "And apostasy is not attributed to him [for] a word that can be interpreted otherwise." And it is stated in An-Nahr al-Fā'iq: "A fatwa of apostasy is not issued against a Muslim if their words can be interpreted in a good way." Ali al-Qari said in Sharh ash-Shifa: "If ninety-nine interpretations point to the apostasy of a Muslim, and one interpretation points to retaining them in their Islam, then the mufti and judge should act upon that one interpretation." Therefore, there is nothing against the questioner as long as the possibility [of a good interpretation] exists, and we advise the questioner to disregard whisperings (waswas) if they are afflicted by them.
