Hazrat Hakam and Hazrat Hammad say that if one kisses or touches, ablution becomes obligatory.

Hazrat Sha'bi says that a kiss breaks the ablution.

Hazrat Hammad says that if a man kisses his wife and the wife does not desire it, then the man's ablution will be nullified but not the woman's. If the woman kisses the man, then ablution will be obligatory on the woman but not on the man. If the man feels desire, then his ablution will also be nullified, and if a man kisses a woman and she does not desire it but he feels desire, then his ablution will be nullified.

Ibrahim said to his wife, "O Haneedah! I praise Allah. If I did not have to maintain my state of ablution, I would have kissed you."

Hazrat Nafi' narrates that Hazrat Ibn Umar (may Allah be pleased with them) kissed a child and then rinsed his mouth.

Hazrat Nafi' narrates that Hazrat Ibn Umar (may Allah be pleased with them) kissed one of his daughters, then asked for water and rinsed his mouth.

Hazrat Nafi' narrates that whenever Hazrat Ibn Umar (may Allah be pleased with them) kissed a child, he would rinse his mouth, but he would not perform ablution.

Hazrat Mughira narrates that I asked Ibrahim about the ruling of performing ablution after kissing a child, so he replied, "This is an expression of kindness and mercy; ablution is not obligatory in this case."

Ibrahim says that if a man touches or kisses (someone) out of desire, his ablution will be nullified.

It is also narrated similarly from Hazrat Sha'bi.
