دعاى امام سجّاد عليه السلام - ايام رجب
اَللَّهُمَّ صَلِّ عَلَىٰ مُحَمَّدٍ وَآلِ مُحَمَّدٍ
O Allah,send blessings to Muhammad and the Household of Muhammad,
يا مَنْ يَمْلِكُ حَواَّئِجَ السّاَّئِلينَ
O one who owns questioners of needs
ويَعْلَمُ ضَميرَ الصّامِتينَ
And the one who knows the conscience of the slient
لِكُلِّ مَسْئَلَةٍ مِنْكَ سَمْعٌ حاضِرٌ وَجَوابٌ عَتيدٌ
On each issue from you heard the present and firm answer
اَللّهُمَّ وَمَواعيدُكَ الصّادِقَةُ واَياديكَ الفاضِلَةُ
In your sincere promises and virtuous hands
ورَحْمَتُكَ الواسِعَةُ
and your vast mercy
فَاَسْئَلُكَ اَنْ تُصَلِّىَ عَلى مُحَمَّدٍ وَآلِ مُحَمَّدٍ
I ask you to send blessings on Muhammad and his household
واَنْ تَقْضِىَ حَوائِجى لِلدُّنْيا وَالاْخِرَةِ
And fulfill my wishes of this world and hereafter
اِنَّكَ عَلى كُلِّشَىْءٍ قَديرٌ
for thou have power over all things
