Snake coming into house but not doing anything then disappearing

Asalamulaikum��Mufti,

There was an incident that happend last week thursday. while I was in Asr Salaah a snake came into my lounge while my kids on the seater. Allah is truly great during my time in salaah the snake and my kids were quiet and there was no movement from the snake and kids. After completing salaah I sensed something and started reciting Durood. I kept on reciting Durood loudly and I was worried about how to get my kids out of the lounge. Strangely after reciting Durood the snake started to move and than I took hazrath ghous paak name as well as asking for assistance and guidance. so when I went through my kitchen door to check on the snake it just disappeared. I do not know what to make of this whole incident because people say that with the snake coming into my house is it bad omen. My faith on that day was really tested.
