What is the status of making khatam of Bukhaari Shareef as a dua for the Palestinians?

Answer

Leave alone Bukhaari Shareef which came into existence a couple of centuries after Rasulullah (Sallallahu alayhi wasallam). Even group khatam of the Qur'aan Majeed for occasions of fear and hardship is not Sunnah. The Sahaabah did not make any such khatam when they were faced by danger and hardship.

Maulana Yoonus Jaunpuri (Rahmatullah alayh) having organized such a khatm in Saharanpur in 1948 is not a daleel in terms of the Shariah. It is the effect of failing to understand reality and of having drifted from the pure Sunnah Tareeqah of the Sahaabah. Even calling for Khatam of the Qur'aan Shareef on such occasions has no substantiation in the Sunnah.

In fact, according to the Hanafi Math-hab, even Qunoot-e-Naazilah is not Masnoon although it is Sunnah according to the other Math-habs. Thus, the practice of group khatam of Bukhaari Shareef on occasions of danger, fear and hardship is akin to Bid'ah. All diversions from the Sunnah ultimately end in the disaster of Bid'ah.
