Hadith (saying of Prophet Muhammad) “War is Deception” narrated by Shiekh Al Hadith Shah Waliullah in his collection “Al Arba’in” (Collection of Forty Ahadiths). In the commentary to this hadith, Shaykh Nematullah stated:
“Achieving victory without armed conflict is more perfect, and this is attained through diplomacy rather than confrontation–since there is no risk of physical danger. It is not permissible to violate peace agreements.”
His collection is different from other 40 Hadith collections by other numerous scholars because his collection of Al Arbai’n are directly narrated through the straight chain of narrations from Hazrat Imam Husain (R.A).
