Shaykh Muhammad Ibn Hizaam was asked:
Is it allowed to use software/apps with voice and picture communication knowing that the picture will go away when the call/connection ends?
“This is a doubtful affair. It is necessary to avoid it and we advise leaving it off. This is because it [the software/app] can store the picture, and then it becomes what is without doubt prohibited. The Prophet (ﷺ) said:
فمن اتقى الشبهات فقد استبرأ لدينه وعرضه
Thus he who avoids doubtful matters clears himself in regard to his religion and his honor
[Agreed upon from the Hadith of Nu’maan ibn Bashir (may Allah be pleased with him)]
And he (ﷺ) said:
دَعْ مَا يُرِيبُك إلَى مَا لَا يُرِيبُك
Leave that which makes you doubt for that which does not make you doubt
[Reported by Tirmidhi and others from Hasan ibn Ali (may Allah be pleased with him)]
So a person should be cautious regarding his religion and avoid doubts”.
Faisal Ibn Abdul Qaadir Ibn Hassan
