"There is no fara' and no' Atirah." (Using translation from Nasāʾī 4222)  

قَالَ رَسُولُ اللَّهِ ﷺ «لَا فَرَعَ وَلَا عَتِيرَةَ»  

[Machine] I said, "O Messenger of Allah, we used to sacrifice during the month of Rajab. What do you think?" He said, "There is no problem with that." Waki said, "I will never leave it."  

قُلْتُ يَا رَسُولَ اللَّهِ إِنَّا كُنَّا نَذْبَحُ فِي رَجَبٍ فَمَا تَرَى؟ قَالَ «لَا بَأْسَ بِذَلِكَ» قَالَ وَكِيعٌ «لَا أَدَعُهُ أَبَدًا»
