Was it the sword or

.I became more than ever convinced that it was not the sword that won a ‰

place for  Islam in those days in the scheme of life. It was the rigid

simplicity, the utter self-effacement of the prophet, the scrupulous regard for

his pledges, his intense devotion to his friends and followers,  his

intrepidity, his fearlessness, his absolute trust in God and in his own

 ission. These, and not the sword carried everything before them and

surmounted every trouble."

Gandhi
