In Islam we are not required to look for the wisdom behind ta`abbudi issues (acts of worship) even if there may be clear wisdoms behind them. The basic ruling regarding acts of worship in following the Qur’an and Prophetic guidance in this concern without looking for the wisdoms and reasons.
Sheikh Sayyed Sabiq, states in his well-known book, Fiqh As-Sunnah: “It is proper for the imam to stand for the two khutbas and to sit for a short while in between them.
Ibn ‘Umar said: “When the Prophet (peace and blessings be upon him) would deliver the Khutbatul Jumu’ah, he did so standing, and then he would sit, and then he would stand [again, for the second khutbah] as the people do today.”
Jabir ibn-Samura said: “The Prophet would deliver the khutbah while standing, and then he would sit, and then he would stand and speak again. Whoever says that he gave the khutbah while sitting has lied. Verily, I prayed with him more than two thousand prayers [including the five daily prayers].”
Moreover, Dr. Muzammil H. Siddiqi, former President of the Islamic Society of North America, states:
“The proper way of Friday and `Eid khutbah is that the Imam deliver the khutbah and then sit down for a short while and then give the second khutbah. This is the Sunnah of the Prophet (
peace and blessings be upon him).
there is no report that the Prophet (peace and blessings be upon him) ever gave one khutbah on Friday or `Eid day. There are many hadiths on this subject reported by several Prophetic Companions (may Allah be pleased with them all).
`Abdullah Ibn `Umar (may Allah be pleased with him) reported that the Prophet (peace and blessings be upon him) used to give two khutbahs and he used to sit between them. (Reported by Al-Bukhari)
the Prophet (peace and blessings be upon him) is reported to have said, “Pray as you have seen me praying.” (Reported by Al-Bukhari) Thus, it is important that we follow his way in our prayers.”
