Hadith 2209
۞
361. Amīr al-mu’minīn, peace be upon him, said: If you have a need from Allāh, the Glorified, then begin by seeking Allāh’s blessing on His Messenger, may Allāh bless him and his descendants, then ask your need, because Allāh is too generous to accept one (seeking His blessing on His Messenger) of the two requests made to Him and deny the other.
٣٦١. وَقَالَ (عليه السلام): إِذَا كَانَتْ لَكَ إِلَى اللهِ سُبْحَانَهُ حَاجَةٌ فَابْدَأْ بِمَسْأَلَةِ الصَّلاَةِ عَلَى رَسُولِهِ (صلى الله عليه وآله)، ثُمَّ سَلْ حَاجَتَكَ، فَإِنَّ اللهَ أَكْرَمُ مِنْ أَنْ يُسْأَلَ حَاجَتَيْنِ فَيَقْضِيَ إِحْدَاهُمَا وَيَمْنَعَ الْأُخْرَى.
