و الأمر بالمعروف
شروط الأمر بالمعروف والنهي
عن المنكر لا بد أن تكون رفيقاً
فيما تأمر رفيقا فيما تنهى عالما
بما تأمر عالما بما تنهى عاملا
بما تأمر عاملا بما تنهى وليس
لك عند الناس إلا بشر الوجه
وطلاقته والقدوة الحسنة.

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised. While no messaging app can guarantee a 100% impermeable defense against determined attackers, Telegram is vulnerabilities are few and either theoretical or based on spoof files fooling users into actively enabling an attack.
