Wasiat yang sama dilakukan oleh R. Nana Djuhana kepada anak angkatnya, Nina Indratna. Skripsi ini membahas mengenai kedudukan saudara dan anak angkat dalam hal pewaris kalaalah menurut hukum kewarisan Islam, serta keabsahan wasiat seluruh harta bagi anak angkat dalam hal masih ada ahli waris yang sah. Penelitian ini menggunakan metode yuridis-normatif dengan tipologi deskriptif. Berdasarkan hasil penelitian diketahui bahwa saudara hanya dapat tampil mewaris apabila pewaris kalaalah dan anak angkat bukanlah ahli waris melainkan penerima wasiat atau wasiat wajibah.
