Arabic hadith text
عَن زيد بن ثَابت وَعَائِشَة قَالَا: الصَّلَاةُ الْوُسْطَى صَلَاةُ الظُّهْرِ رَوَاهُ مَالِكٌ عَن زيد وَالتِّرْمِذِيّ عَنْهُمَا تَعْلِيقا
Translation
Zaid b. Thabit and ‘A’isha said that the middle prayer is the noon prayer. Malik transmitted it from Zaid and Tirmidhi from both of them without a full isnad.
