Is it permissible for me to perform Tayammum (dry ablution with clean earth) when I am in my pastureland, although I have some water to drink and my village is one kilometer or more away?
It is not permissible for you to perform Tayammum to offer Salah (Prayer) in such a case, because the distance to the place where water is available is close. Most likely, there is no difficulty in going there to bring some water. The due time of Salah is not missed by going to bring water from your village. Moreover, you can provide yourself with enough water for your drinking and Wudu' (ablution), if you fear the loss of any of the cattle you pasture. You can also use whatever tools that make it easy to provide yourself with enough water. (Part No. 4; Page No. 180) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
