The tithe collector making anyone swear or searching him

Abdullah bin Ma'qil was appointed to collect the tithes, and he used to make people swear oaths. Abu Wa'il passed by him and said to him: Do not make people swear about their wealth; why do you throw them into Hell? Abdullah bin Ma'qil said: If I do not make them swear, they will not pay anything. He said: Their not paying anything is better than your making them swear.

It is narrated from Abu Ishaq that Masruq was at a place called al-Silsilah. Whoever passed by him, whatever he gave him, he would accept, and he would say: Is there anything in what you have in which we have a right? If he said yes, (he would collect it); otherwise he would say to him: Go.

It is narrated from Qurrah: I passed by Humayd bin Abd al-Rahman in a boat. He said: He did not let me go until he made me swear as to what was in it.

Ziyad bin Hudayr said: Sayyiduna Umar (may Allah be pleased with him) sent me to collect the tithes, and ordered me not to search anyone.

Tawus said: The tithe collector is only to advise and guide the traveller, and whoever comes to him with something, he accepts it from him.
