Sayyiduna Abdullah ibn Umar (radhiyallu 'anhuma) didn't see a problem with calling upon the dead either in the narration عن عبد الرحمن بن سعد قال: خدرت رجل ابن عمر فقال له رجل: اذكر أحب الناس إليك فقال: يا محمد Abdur Rahman ibn Sa’d narrates Ibn Umar (radhiyallahu 'anhum) had numbness in his leg, whereupon a man said to him, "Remember the most beloved of people to you", so he said, "Ya Muhammad". [Imam al Bukhari, Kitab ul Adab ul Mufrad, Hadith 964] Imam 'Ali al Qari (rahimahullah) explains كانه رضى الله تعالى عنه قصد به اظهار المحبة فى ضمن الاستغاثة Ibn Umar (radhiyllahu 'anhuma) expressed his love in the form of "ISTIGHATHA" ['Ali al Qari: Sharh ash-Shifa (2/41)]
