This was translated elsewhere as:
Hazrat `Allamah ibn `Abidin [rh] on the footnote of his internationally renowned book Raddul Muhtarul Ma'roof says that Ziyadi has reported that if any person loses any one of his belongings and he wishes for Almighty Allah to return it to him, he should stand on a high place facing the Qibla and make Fatiha and send the reward to the Holy Prophet [sallallahu `alayhi wa sallam] and to Sayyid Ahmad bin Alwan [rh] and say,
“O my leader Ahmad! O son of Alwan! If you do not return my lost item, then it is fine, otherwise I will remove your name from the register of the Awliyah
يَاسَيِّدِىْ اَحْمَدُ يَابْنَ عَلْوَانَ اِنْ تَرُدَّ عَلَىَّ ضَالَّتِىْ وَاِلاَّ نَزَعْتُكَ
مِنْ دِيْوَانِ اْلاَوْلِيآءِ فَاِنَّ اللهَ تَعَالىَ يَرُدُّ عَلىَ
With the Barkah of this amal and that Wali Allah, the lost thing will be returned.”
مَنْ قَالَ ذَالِكَ ضَالَّتَه‘ بِبَرْكَتِهِ اُجُوْرِىْ مَعَ زِيَادَةٍ
[Rad al Muhtar ala Dur al-Mukhtar Pg.334 Vol.3]
Insha'Allah a better translation will follow.
