Mukhtasar Bukhari (Abridged) 1271 — Taking pledge in battle not

´Sayyiduna Ibn Umar (may Allah be pleased with them both) says that (after the Pledge of Ridwan) when we came again the following year, not even two men among us could agree on identifying the tree under which we had pledged (Ridwan). (There was some mercy from Allah in this.) It was asked: On what matter was the pledge taken from the Companions (may Allah be pleased with them all), was it on death? He replied: No, rather the pledge was taken on patience.
