It is narrated from Sayyiduna Talhah (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) passed by some people who were in the date orchards. The Prophet (peace and blessings be upon him) asked, "What are these people doing?" The people replied that they were pollinating the female date palms with the male ones. The Prophet (peace and blessings be upon him) said, "I do not think that this brings any benefit." When those people heard this, they did not perform this act that year. When the Prophet (peace and blessings be upon him) came to know of this, he said, "If they benefit from it, then they should do this work. I only expressed a thought and an opinion, so it is not necessary for you to act upon my opinion. However, when I tell you something regarding Allah, then act upon it, because I can never lie about Allah in any way."
