يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ وَابْتَغُوا إِلَيْهِ الْوَسِيلَةَ وَجَاهِدُوا فِي سَبِيلِهِ لَعَلَّكُمْ تُفْلِحُونَ

✦ Al Quran : O you who believe! Do your duty to Allah and fear Him. And Seek the means of approach (Tawassul)  to Him, and strive hard in His Cause so that you may be successful.

Surah Al-Maaida (5), Verse 35

Hadith: Narrated Anas Radhi Allahu Anhu Whenever drought threatened them, 'Umar bin Al-Khattab, used to ask Al-Abbas bin 'Abdul Muttalib to invoke ALLAH for rain. He used to say, "O ALLAH! We used to ask our Prophet Peace be upon him to invoke You for rain, and You would bless us with rain, and now we ask his uncle to invoke You for rain. O ALLAH ! Bless us with rain."And so it would rain.
