DARIMI 1473:
from Rijāl Marḍiyyūn Fīhim ʿUmar b. al-Khaṭṭāb And ʾArḍāhum ʿIndī ʿUmar —
Some reliable people testified before me, and among them was Umar ibn al-Khattab, and most reliable in my eyes was Umar: The Prophet of Allah ﷺ said: There is no prayer after the dawn prayer until the sun rises; and there is no prayer after the 'Asr prayer until the sun sets. (Using translation from Abū Dāʾūd 1276)
الدارمي ١٤٧٣:
عن رجال مرضيون فيهم عمر بن الخطاب و ءرضاهم عندي عمر —
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا صَلَاةَ بَعْدَ صَلَاةِ الصُّبْحِ حَتَّى تَطْلُعَ الشَّمْسُ وَلَا صَلَاةَ بَعْدَ صَلَاةِ الْعَصْرِ حَتَّى تَغْرُبَ الشَّمْسُ»
