Hadith 1185
وَعَن حُذَيْفَة نَحْوَهُ وَزَادَ فَكَانَ يَقُولُ: «عَجِّلُوا الرَّكْعَتَيْنِ بَعْدَ الْمَغْرِبِ فَإِنَّهُمَا تُرْفَعَانِ مَعَ الْمَكْتُوبَةِ» رَوَاهُمَا رَزِينٌ وَرَوَى الْبَيْهَقِيُّ الزِّيَادَةَ عَنْهُ نَحْوَهَا فِي شُعَبِ الْإِيمَان
Hudhaifa has something similar, adding that he used to say, “Hasten the two rak'as after the sunset prayer, for they will be taken up along with the prescribed prayer.” Razin transmitted them both, and Baihaqi transmitted something to the same effect as the addition in Shu'ab al-iman.
