It is narrated from Sayyiduna Laqit bin Amir (may Allah be pleased with him) that he asked the Prophet (peace and blessings be upon him) about ablution (wudu), and he (peace and blessings be upon him) said: "When you are fasting, then (after putting water in your nose) blow it out gently."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Muhammad bin Tariq (may Allah have mercy on him) except Bishr (may Allah have mercy on him), and Safwan (may Allah have mercy on him) is alone in transmitting it."
