َّدٍ عَنْ عَلِيِّ بْنِ حَدِيدٍ قَالَ كَتَبَ إِلَيْهِ عَلِيُّ بْنُ ٠ُيَسِّرٍ يَسْأَلُهُ عَنْ رَجُلٍ اعْتَ٠َرَ فِي شَهْرِ رَ٠َّ حَضَرَ لَهُ الْ٠ُفْرِداً لِلْحَجِّ أَوْ يَتَ٠َا أَفْضَلُ فَكَتَبَ إِلَيْهِ يَتَ٠8.

Ahmad ibn Muhammad from has narrated from Ali ibn Hadid who has said the following: “Once Ali ibn Muyassir wrote to him (the Imam) asking about a man who performed al-‘Umrah in the month of Ramadan, then it was al-Hajj season; if he could perform al-Hajj as al-Mufrid al-Hajj or al- Hajj al-Tamattu‘ (advantageous), and which one was better.

He (the Imam) wrote in answer, ‘Al-Hajj al-Tamattu‘ is better.’” ضعيف - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (17/189))
