What is mentioned from Abdur Rahman bin Awf and Abu al-Darda

Sa'id bin Jubayr said that Abu Hayyaj al-Asadi said: I heard an old man who was circling the House of Allah in Tawaf and was also making this supplication: "O Allah, protect me from the stinginess of my own soul." I did not know who the old man was. Then, when he turned to leave, I walked behind him and asked about him, and the people told me: "This is Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him)."

Thumamah bin Hazn said: I heard an old man supplicating in this way: "O Allah, I seek refuge with You from an evil with which nothing else has been mixed." Thumamah said: I asked: "Who is this old man?" The people said: "Sayyiduna Abu al-Darda (may Allah be pleased with him)."
