Shaykh Salih says in the intro to the print of this poem titled: The Gladdening of the Heart of the People of Love and Affection in the Praise of the Family of the Best of Mankind (also known as Ahlu Bayti ‘l Mustafa):
(مفرحة الفؤاد لاهل الحب والوداد في مدح آل بيت خير العباد)
“Some of the brothers saw Sayyidah Fatimah (peace be upon her) in their dreams by reciting this poem and she said:
‘The Prophet ﷺ will come and give the reciters of this qasida drink from the water of Zamzam.’
And he ﷺ has come, and given all those in attendance drink. And some of the brothers witnessed, in a wakeful state, these lights and secrets and others witnessed the meaning of the line mentioned in the Burdah al-Hasaniyya al-Husayniyya:
‘Indeed they are present at the commemoration of their praise
In the gatherings of praise, so take advantage of their presence’
To the extent of the unveiling will this attribute be realized, to the extent of one’s love will be the state of nearness, to the extent of one’s affection will be the attainment of spiritual support, to the extent of one’s following will be the attainment of election, and to the extent of the purity of one’s vessel will be the outpouring of spiritual meanings.”
