Musannaf Ibn Abi Shaybah

Hasan was asked about the person whose limb dries before completing ablution. He said: If he has not done anything other than ablution, then he should wash his feet, and if he has done something else besides ablution, then he should perform ablution again.

Hazrat Waki’ says that I asked Hazrat Sufyan about this matter, so he replied that he will wash his feet. I asked, “Even if any of his limbs become dry?” He replied, “Yes, even if any of his limbs become dry.” Hazrat Waki’ says that this is also our belief.

Hazrat Mujahid states that Hazrat Jabir and Hazrat Sha'bi considered it undesirable for a person in a state of major ritual impurity (junub) to write "Bismillah ir-Rahman ir-Rahim."

Ibrahim says that the predecessors did not consider it proper for a person to write a letter without ablution.

Hazrat Abu Huzail states that the predecessors used to remember Allah in every state except for the state of major impurity (janabah).
