Yazid bin Abi Ubayd said: I heard Sayyiduna Salamah bin al-Akwa' (may Allah be pleased with him), who attributed it to the Prophet, if Allah wills, that when the wind grew strong the Prophet (peace and blessings be upon him) would say: 'Allahumma laqahan la 'aqiman' (O Allah, make it beneficial, not harmful).
