Fourthly, the first month of the Hijri year, Muharram, is a sacred month which has a number of key virtues. Some scholars considered it as the best month after Ramadan.
Abu Uthman Nahdi (rahimahullah), a great Tābi’i, says, “They (ie. the Sahaba) would honour/ respect three sets of ten days: (1) the last ten days of Ramadan (2) the first ten days of Dhul-Hijjah (3) the first ten days of Muharram.” It was also reported by ‘Abd al-Razzāq in al-Musannaf that Ibn Umar rarely did not fast in the sacred months.
It has been narrated from the Prophet (sall Allāhu ʿalayhi wa sallam) that after Ramadan, the most rewarding time to fast is in the month of Muharram. It was narrated that Abū Hurairah (raḍiy Allāhu ʿanhu) said, “The Messenger of Allāh (sall Allāhu ʿalayhi wa sallam) said: ‘The best fasts after Ramadan is the month of Allāh – Muharram, and the best prayer after the obligatory prayer is prayer at night.’”
The Prophet called this month the month of Allāh as an indication of its great status.
Al-Hāfidh al-Suyūti said: I was asked as to why Muharram is singled out as the “month of Allah” from the rest of the months, although other months have equal merit or even more than it, such as Ramadan. I found the following answer: for this is an Islamic name unlike the rest of the months, for their names were there during the times of Jāhiliyya (Ignorance). As for the name Muharram it was known as Safar al-Awwal during Jahiliyya, after it was Safar al-Thāni. When Islam came Allah called it Muharram, so it was attributed to Allah because of this consideration.
