Sayyiduna Zaid bin Arqam (may Allah be pleased with him) narrates that a man would talk to the person standing next to him in prayer until this verse was revealed « وَقُومُوا لِلَّهِ قَانِتِينَ » [ سورة البقرة : 238 ] "And stand before Allah with humility." In the narration of Janab Huthaym, there is this addition: So we were commanded to remain silent and forbidden from speaking.
