It is not from the sunnah to go and check as long as there is not reason for checking! This would open the door for the whispers of Satan and make you an OCD patient.

If I do a small qailoula (45 min) and then I wake up and I go to bahtroom to do my necessites and then do wudhu for asr prayer, but I didnt checked if some madhi was there what should I do? Notice shaykh that as I went to do my necessities I washed the thing with water. However, in case there was madhi I didnt washed clothes.But as I said you I dont even know if there was .
