Caution and fear regarding oaths

It is reported about Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) that he paid ten thousand dirhams as ransom in place of his oath, and then said: "By the Lord of the Ka'bah, had I sworn, I would have sworn truthfully; but this is something I have given as ransom in place of my oath."
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and its narrators are thiqat (trustworthy).

Sayyiduna Ash'ath bin Qays (may Allah be pleased with him) said: Once I bought (back) my oath for seventy thousand.
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Isa bin al-Musayyab al-Bajali, who is da'if (weak).

Abd al-Qahir bin al-Sari narrated: A man hid at the home of Abu al-Sawwar al-Adawi; this was in the time of al-Hajjaj bin Yusuf. Al-Hajjaj was told that the man was at Abu al-Sawwar's home. Al-Hajjaj sent for him, and when he came, al-Hajjaj asked him: "Is the man with you?" He replied: "He is not with me." Al-Hajjaj said: "If that is not so, then the mother of al-Sawwar, that is, the wife of Abu al-Sawwar, is divorced." He said: "When I left her, I did not intend to divorce her." Al-Hajjaj said: "Very well, then you will be free of Islam." He asked: "Then where will you go?" So al-Hajjaj let him go.
Imam al-Tabarani recorded it in al-Mu'jam al-Saghir, and its narrators are thiqat (trustworthy).
