In one narration the wording is: I was with the Prophet (peace and blessings be upon him). Deeds were mentioned, and he said: "There are no days in which doing a deed is more beloved to Allah Almighty than (doing it in) these ten days." After that the narrator mentioned the hadith as before.
Ahmad recorded it, and al-Tabarani recorded it in al-Mu'jam al-Kabir; both are reported with two chains each, and the narrators of one of them are thiqat (trustworthy).
