Sunan Ibn Majah, Volume 4, Book 25, Hadith 2952 (DarusSalam) ⓘ

It was narrated from Zaid bin Aslam that his father said: “I heard ‘Umar say: ‘Why do they perform Ramal now, when Allah has established Islam and done away with disbelief and its people? By Allah,* we will not give up something that we used to do at the time of the Messenger of Allah.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَعْفَرُ بْنُ عَوْنٍ، عَنْ هِشَامِ بْنِ سَعْدٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ عُمَرَ، يَقُولُ فِيمَ الرَّمَلاَنُ الآنَ وَقَدْ أَطَّأَ اللَّهُ الإِسْلاَمَ وَنَفَى الْكُفْرَ وَأَهْلَهُ وَايْمُ اللَّهِ مَا نَدَعُ شَيْئًا كُنَّا نَفْعَلُهُ عَلَى عَهْدِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ ‏.‏
