Did you break wind or was it Shaytân pulling a hair?
Also, how to prevent any waswasah in regards to urine-drops
Gasses during prayer or Shaytan pulling a hair from your back?
Abu Sa’id al-Khudri (radhiya Allahu ‘anh) reported that the prophet (salla Allahu ‘alayhi wa sallam) said: “The devil may approach one of you during Salah, and pull a hair from your back. If the man were to imagine that his ablution had been broken, he should not leave his prayer, unless he should hear a sound or perceive a smell.” (Recorded by Abu Dawud)
(Waswasah: The whispering of the Shaitan, p. 44)
What to do in order to prevent any Waswasah in regards to urine drops after answering the call of nature?:
Shaykh Abu Muhammad bin Qudamah al-Maqdisi said:
“It is recommended to sprinkle one’s private part and trousers with water after urinating (in the toilet), in order to prevent any waswasah. And so, if one finds any wetness in his clothing, he would say: “This is the water that I sprinkled there.” al-Hakam bin Sufyan at-Thaqafi (radhiya Allahu ‘anh) reported that when the prophet (salla Allahu ‘alayhi wa sallam) urinated, he performed ablution and sprinkled water on his private parts.” (Recorded by Abu Dawud)
(Ibid, p. 44)
These two gems are great reliefs for those who are affected by the whispers of Shaytân. You will see them remaking Wudhu’ and prayers for several hours and in the end they even imagine that they have the disease of a 60 year old man, while just a month or two ago before they started to pray, they were totally healthy.
