Muhammad bin al-Munkadir narrated from Sayyidah Umm Hani (may Allah be pleased with her): "He (peace and blessings be upon him) ate shoulder meat and then prayed without performing ablution again." What she meant was that the Prophet (peace and blessings be upon him) did this.
Imam al-Tabarani recorded this report in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat, and its narrators have been declared trustworthy.
