From Sahih Bukhari (Hadith 4609):
Narrated `Abdullah (bin Masud):On the day of Badr, Al-Miqdad said, "O Allah's Messenger (ﷺ)! We do not say to you as the children of Israel said to Moses, 'Go you and your Lord and fight you two; we are sitting here, (5.24) but (we say). "Proceed, and we are with you." That seemed to delight Allah's Messenger (ﷺ) greatly
