Hazrat Ismail bin Abi Khalid narrated in the manner of Bundar’s previous hadith, but he stated these words: In the time of the Prophet (peace be upon him), a person would speak to his companion during prayer if necessary, until this verse was revealed « وَقُومُوالِلَّهِقَانِتِينَ »[ سورة البقرة : 238 ] "And stand before Allah with devotion." Then we were commanded to remain silent.
