It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that some Bedouins came to the Prophet (peace and blessings be upon him) and said: We live in a sandy place, and we stay away from water for two or three months, and among us are people in a state of janabah and menstruating women. He (peace and blessings be upon him) said: "Hold to the earth."
Abdullah bin Salamah al-Aftas is da'if (weak).
