Lady Asma (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) ordered the freeing of slaves at the time of a solar eclipse. The Imam reports from the chain of narration of Janab Darawardi, in which the words are that he ordered the freeing of slaves at the time of a solar eclipse.

Bishr Taykah, if the narrated hadith in this chain is authentic, because I do not think that Abu Qilabah heard from Sayyiduna Nu'man bin Bashir (may Allah be pleased with him), and I have also not been able to find out whether Qabeesah is a companion or not.
