What the Prophet ﷺ said on hearing thunder, in strong wind, when asking for rain and after rainfall, together with the dua for sighting the new moon.
Allāhumma innī as'aluka khayrahā, wa a`ūdhu bika min sharrihā.
O Allah, I ask You for the good of it, and seek refuge in You against its evil.
Abu Dawud 4/326
Allāhumma innī as'aluka khayrahā, wa khayra mā fīhā, wa khayra mā ursilat bih, wa a`ūdhu bika min sharrihā, wa sharri mā fīhā, wa sharri mā ursilat bih.
O Allah, I ask You for the good of it, for the good of what it contains, and for the good of what is sent with it. I seek refuge in You from the evil of it, from the evil of what it contains, and from the evil that is sent with it.
Muslim 2/616
Subḥāna ‘l-ladhī yusabbiḥur-ra`du bi ḥamdihi wa ‘l-malā'ikatu min khīfatih.
Glory is to Him Whom thunder and angels glorify due to fear of Him.
Allāhumma ‘asqinā ghaythan mughīthan marī'an murī`a, nāfi`an ghayra ḍārr, `ājilan ghayra ājil.
O Allah, shower upon us abundant rain, beneficial not harmful, swiftly and not delayed.
Abu Dawud 1/303
Allāhumma aghithnā, Allāhumma aghithnā, Allāhumma aghithnā.
O Allah, send us rain. O Allah, send us rain. O Allah, send us rain.
Al-Bukhari 1/224
Allāhumma’sqi `ibādaka wa bahā'imak, wanshur raḥmatak, wa aḥyi baladaka ‘l-mayyit
O Allah, give water to Your slaves, and Your livestock, and spread Your mercy, and revive Your dead land.
Abu Dawud 1/305
Allāhumma ṣayyiban nāfi`a.
O Allah, (bring) beneficial rain clouds.
Al-Bukhari
Muṭirnā bifaḍlillāhi wa raḥmatih.
We have been given rain by the grace and mercy of Allah.
Al-Bukhari 1/205
Allāhumma ḥawālaynā wa lā `alaynā. Allāhumma `ala ‘l-ākāmi waẓ-ẓirāb, wa buṭūni ‘l-awdiyati, wa manābitish-shajar.
O Allah, let the rain fall around us and not upon us, O Allah, (let it fall) on the pastures, hills, valleys, and the roots of trees.
Al-Bukhari 1/224
Allāhu Akbar, Allāhumma ahillahu `alayna bi ‘l-amni wa ‘l-īmān, was-salāmati wa ‘l-'Islām, wat-tawfīqi limā tuḥibbu Rabbanā wa tarḍā, Rabbunā wa Rabbukallāh.
Allah is the Most Great. O Allah, bring us the new moon with security and Faith, with peace and in Islam, and in harmony with what our Lord loves and what pleases Him. Our Lord and your Lord is Allah.
